So, you're theory is that what happened in the past was not directly observed by us and therefore could have been different than it is now.
Okay, then here's my theory: The world was created exactly as it, including these forums along with my previous posts, at exactly 10:33 am PST on what we call July 22nd, 2007.
Everything was created, including our memories, in order to give us the appearence of it being older or that we had been around longer.
Before 10:33am everything was "different".
Good luck disproving me.
A perfect pre-flood world.
This is an incredibly short sentence and you've still managed to get it wrong.
You hypothesize that there was a different world "pre-flood" however, since we know there was no flood, this hypothesis falls flat on it's face.
