Hm the lifeless universe we observe. Uh unless you include observing earth. Duh. Also, outside of our solar system I’m unaware of “observations” sufficient to determine other planets are lifeless. In fact I’m certain we have no such observations.

...

This is the point I always make. Life being extremely rare fits every observation we have so far.

The proportion of biomass to mass here on Earth is actually very small. It took life over 3.5 billion years to appear on land. And there are multiple critical events in evolution that occurred only once or very few times.

One thing we do know for sure is that life is possible in the Universe, because we’re here.

There is this planet that is run by monkeys.

No....that’s California.

Because I believe God has populated other worlds.

We know of heaven. That’s located somewhere in the universe.

Or perhaps we are preparing a place for God. Humans were critical in bringing Jesus here.

If you assume the absence of a creator (I’m not suggesting it, just throwing it out there), then the chances of life forming have to be non-zero. We’re here, therefore life can exist.

Even if we’ve won the life lotto but the chances are minuscule, the universe is a darned big place. Tiny probabilities factored against the vastness of the universe give pretty significant numbers, at least to our frame of reference. Whether the timing and distance allow us to know of any life-form brethren is a separate question.

But bringing God back in, He gave us quite a bit of guidance, but there’s plenty He left out for us to figure out on our own. Given how difficult we know it would be to contact another civilization, and even now we haven’t made any progress finding one to contact, it wouldn’t seem like God would need to mention we were or weren’t unique in the universe. What difference would it have made either way? “Though thou aren’t alone, don’t bother looking for you thou won’t find anyone else anyway” doesn’t exactly help us live our daily lives.

Yes. It is so.

If we expand our horizon past the visible to the entire universe, we’d find not only is it teeming with life, but there are planets with humanoids, which has president(s) with yellow hair making their planets great again.

13 billion miles is 0.0022 light years. I believe we can see much further than that.

Because it does exist, here.

So there’s at least one.

Is there more?

I honestly don’t know.

Or looking at it another way, are we alone?

I honestly don’t know that either.

I sometimes wonder if there really has been enough TIME since the Big Bang (BB) for life to florish.

The Sun and Earth are about 4 billion YO, and the BB was 13 billion Years ago.

However, the Solar System has a lot of heavier than Hydrogen/Helium elements. The heavier elements are actually made in gigantic supernova’s—exploding massive stars.

How many cycles of this manufacturing did it take to make enough heavier elements to make a planet the size of Earth, full of Silicon, Iron, Carbon, Nitrogen, Aluminum, Manganese, Sodium, Sulfur, Oxygen,, and all the other elements necessary for life? We’re carbon-based... So we had wait for that element. We also need lots of oxygen, at least to make water.

Maybe it takes 8-9 billion years of exploding stars just to get enough heavier elements into the universe to start making life?

Maybe we’re just the first?

a Ph.D in computational neuroscience, a nanotechnology researcher, and a moral philosopher

So, what are his credentials to pontificate on this subject?

That should be 13 billion LIGHT-YEARS.

That is the farthest we can sense. The steady hum of a hydrogen soup, shortly after the Big Bang.

As a Christian, I wonder. God’s only begotten Son died for our sins. If there is sentient life on other planets, they would have to be composed of either obedient beings, who, unlike Adam and Eve, passed the test, and are perpetually perfect; or totally corrupt, irredeemable beings, whom God has abandoned completely. And since we live and breathe at His pleasure, the latter is not likely. And since there’s only one God, and one Jesus, I can see no other alternative. I look forward to eternity, when whatever the truth of the matter is, it will be made known to me. Some people believe that Heaven is composed of many beautiful planets, which we will be able to visit.

“Because I believe God has populated other worlds.”

Believing is not the same as knowing, is it?

“I honestly don’t know.”

I honestly don't either. I'm open to the possibility, and all the sci-fi fi stories of exotic civilizations millions of miles away are great fun, but I cannot understand why anyone would be certain.

I’m alone in my observable universe, as well, although I’m pretty sure there is some asshole next door.

The “observable” universe is kinda tricky to explain, but I’ll try. The farthest things we can see are the things whose light took this long to reach us (ie: since creation / big bang). They are, of course, very, very far away.

Anything further out than that and the light hasn’t reached us yet, but it might some day. It is impossible for us to know if there is anything beyond the observable universe because no radiation (light or otherwise) could have reached us yet.

I sense a disturbance in the Force as if someone is talking about me.

“extant scientific knowledge corresponds to uncertainties that span multiple orders of magnitude … When the model is recast to represent realistic distributions of uncertainty, we find a substantial probability of there being no other intelligent life in our observable universe, and thus that there should be little surprise when we fail to detect any signs of it.”

This is ridiculous, we have exactly one example of life, us. So how the heck can models be recast and find ‘substantial probability’ of anything?

There are many theoretical solutions to the paradox as far as I can see. They are all just as valid as a theory saying that we are alone simply because we can’t detect anything and haven’t been visited by anyone else so far.

The biblical argument against life elsewhere is that Christ died for all mankind. Did he die for mankind somewhere else too? Did he die ... over there too? Or did he choose Earth on a whim, but made it into those other people’s bibles?

It only takes one jerk race to decide that they have to be the only ones to exist in the galaxy. All it takes is set of self-replicating automated probes operating on fairly simple software. They can travel at sublight speed, search for coherent radio signals, and home it on them. When they get a lock they then shove an asteroid to set it on a collision course with the signal source. Then they make more probes from raw material in the ejecta and go out again.

The TV signals for ‘I Love Lucy’ are now 60 light years out. It might only be a matter of time
