-Removed-Its not at all clear whether your are agreeing with sonhouse or disagreeing and if you are disagreeing on what point.
But your earlier statement
... wind back time far enough and there probably wasn't much undulation of the Earth's crust, just a large flat area.
Is definitely incorrect. Although I concede that it is remotely possible that the earth was largely flat, it is highly unlikely and certainly not probable as you suggest and your argument that it was simply showed that you didn't think it through.
-Removed-That depends on what you mean by 'far less'. I would certainly say that your original description of 'just a large flat area' is very very improbable.
If you look around the world you will be hard pressed to find any large flat areas. For all the land to be like that would require some specific phenomena to cause it and unless we know of one, it remains highly unlikely.
For the record, I never agree with sonhouse.
Just for the fun of it?
-Removed-You haven't seen the mountains on the moon? They did not come from tectonic activity. They came from asteroid strikes. Early Earth had the same strikes and would have had the same kind of mountains, but they would have been torn down and built back up again by subsequent strikes so early Earth could not have been flat.
BTW, you would have bugs in your computer too if you had several teenagers using it.
-Removed-Give some sort of reasoning as to why you think it probable that the earth was flat.
Keep in mind that there is no reason to believe that there hasn't always been tectonic activity, and that every planet or moon that we have looked at to date has mountains and valleys.
Can you suggest a process that would lead to a very flat earth?
