Following along the same lines as a geologist would, after observing water eroding rock and soil, that huge canyons can form

BTW, it's obvious that huge canyons can form, or have been formed, because we see them. How this happened is a little less obvious. Anyone who believes the fairy tale about how the Grand Canyon was formed by the ground rising up around this little river just isn't observing. (Hint: Look at the side canyons.)

"Maybe you've noticed I haven't made an argument yet?"

Earlier you explicitly asked:

"Really? We observe other solar systems forming?"

This interrogative questions the other poster's position, and implies the following:

(1) You are either un-aware of the current state of astronomical observations, - or -

(2) You don't accept the principle that you can make observations of multiple objects and phenomena at different stages in order to deduce the progress of a SINGLE object or phenomenon where the timescales are far greater than human lifespans allow.

It's just not a good argument.

"...it's obvious that huge canyons can form, or have been formed, because we see them..."

You can say the same thing about Stars and Planets. We see them as well.

"...the Grand Canyon was formed by the ground rising up around this little river..."

My geological example had to do with EROSION, which is the process by which soil and rock are REMOVED by water. I honestly don't know where you are getting the "ground rising up" reference.

Again, not a good argument.
