There is a rational and scientific explanation, but for it to be true. a lot of factors had to come together at the same time. 300 million years ago, Earth very likely had lower gravity and certainly had a far higher concentration of oxygen - such that a dinosaur living in our time would be crushed by its own weight while dying of lack of sufficient oxygen. "Another perhaps more believable theory is that during the Mesozoic, Earth had a slightly higher rotation rate which would lessen gravity slightly. More importantly the Earth's atmosphere was much thicker than today, giving more buoyancy to large animals. Slightly lower gravity, air 2/3rds that of water and very large animals become possible. "ρF = ρS (1 - 1/S.F.) where ρF is the density of the fluid, ρs is the density of the substance submerged in the fluid such as the dinosaur, and S.F is the scaling factor. "Inserting into this equation a scaling factor of 3.2 and an overall vertebrate density of 970 kg/m3, the Earth's atmospheric density during the late Jurassic period can be calculated to be 670 kg/m3. This says that to produce the necessary buoyancy so that the dinosaurs could grow to their exceptional size, the density of the Earth’s air near the Earth’s surface would need to be 2/3’s of the density of water. (ref: https://dinosaurtheory.com/solution.html)" I didn't write that but t does sound somewhat possible. Having lots of air sacks would help with the buoyancy ... bu density is another problem - once it turns to stone (fossilizes), how can you determine the real life density?

“Bones don’t decay?”

You have an interesting point. On our property at least 1 deer will winter kill, whether it be from coyotes getting it, a stray hunter’s bullet or disease. My point is, in the spring all we will find is the hair. Lots of it. The bone, hoof and tooth matter simply do not exist.

I trapped out several beaver a few years back and piled the bodies on the shore. Couple weeks later all that was left was the snares and a few claws. No bones, no teeth, nothing else.

My point is, something eats this stuff before it has a chance to rot.

So the probability of finding millions of prehistoric bones is really minimal unless the conditions were ripe for them to be fossilized.

Are you saying the Brontosaurus fossils are fakes?

Day and night were created BEFORE the sun was created.

How can you base the length of a day on the sun?

Do you realize how silly that sounds? Gravity was weaker?
Evolutionists need to be consistent, either things constantly vary or they don’t. Fitting the facts to the narrative is very disenguous.
Maybe days were longer, or maybe shorter, maybe there was lower or higher air pressure, 220,221, whatever it takes.
Maybe just better left said “we don’t know” rather than constantly mix and match theories that do not support one another.

That’s the time it takes for the earth to spin once on it’s axis :)

Yup. It's quit common for dogs to eat bones, if given the chance. That's just one example.

[1:1] In the beginning when God created the heavens and the earth,
[1:2] the earth was a formless void and darkness covered the face of the deep, while a wind from God swept over the face of the waters.
[1:3] Then God said, “Let there be light”; and there was light.
[1:4] And God saw that the light was good; and God separated the light from the darkness.
[1:5] God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day.

What kind? Back in the 1950s, college days, my botany professor didn’t seem to know. Can’t be suction pump.

Scattered hair and a pile of undigested willow twigs is all that remains in the spring of the body of a winter-killed moose. I’ve seen scores of such piles in northern B.C.

From a Scientific American article:

.. The physiology of water uptake and transport is not so complex either.
The main driving force of water uptake and transport into a plant is transpiration of water from leaves.
Transpiration is the process of water evaporation through specialized openings in the leaves, called stomates.
The evaporation creates a negative water vapor pressure [that] develops in the surrounding cells of the leaf.
Once this happens, water is pulled into the leaf from the vascular tissue, the xylem, to replace the water that has transpired from the leaf.
This pulling of water, or tension, that occurs in the xylem of the leaf, will extend all the way down through the rest of the xylem column of the tree
and into the xylem of the roots due to the cohesive forces holding together the water molecules along the sides of the xylem tubing.
(Remember, the xylem is a continuous water column that extends from the leaf to the roots.)
Finally, the negative water pressure that occurs in the roots will result in an increase of water uptake from the soil.

Well, TK, does that make sense to you? My botany professor said that is the customary explanation, but that the suction pump, which this would be, tops out at a water head of about 32 feet, which is all a vacuum pump can bring to bear. That's why he said that he did not have an explanation.

Now, I haven't done any literature research on the actual process, but I do have a BS in Engineering and a PhD in physical chemistry. However, a convenient explanation doesn't seem to appear,just off-hand.

In a deep well, there has to be a mechanical pump that pushes the water up to the earth's surface, usually into a water tower, to obtain a practical pressure to distribute the water by gravity. I doubt if a centrifugal pump would work deep down, either. after 30 feet max, it would just sit there and cavitate, wouldn't it?

For a tree, water going up inside would be atmospheric pressure to the roots, wouldn't it? The water has to come from somewhere. And I would think that if the ambient was 100% relative humidity, there could be no negative pressure developed by evaporation, eh?

To me, the Scientific American explanation is a bit inadequate, isn't it?

Well FRiend, I'm just an old carpenter/cabinetmaker, but my take on the little bit I've read/grasp is that the key is the teamwork of capillary action, cohesion, and surface tension.

I found this, here: The USGS Water Science School

Plants and trees couldn't thrive without capillary action. Plants put down roots into the soil which are capable of carrying water from the soil up into the plant. Water, which contains dissolved nutrients, gets inside the roots and starts climbing up the plant tissue. Capillary action helps bring water up into the roots. But capillary action can only "pull" water up a small distance, after which it cannot overcome gravity. To get water up to all the branches and leaves, the forces of adhesion and cohesion go to work in the plant's xylem to move water to the furthest leaf.

- - - - - -

Which is a lot better summary of what I'd always heard/read about the way it works.
Given my (now retired) craft, I'm just glad it works, however trees actually do it  :-)

I told you it sounded like heresy.

Point is, the bones exist, therefore the animals existed on this planet at some point.

Two: the size of the bones indicates that many of these animals were much, much larger than any animals we see on the planet today. So large, in fact, that they could not exist on earth with its present gravity.

There must be some logical explanation for this, as condition one and condition two cannot co-exist. Gravity on earth could not have been as strong as it is today, or those massive fossils would not be in the ground. Those animals could not have existed at all, if the planet's gravity were as strong then, as it is now.

How could our planet's gravity have been weaker? We do not know. We can only assume that it must have been, and that someday we'll find the answer.
