I feel I've learned that plenty of times. I've heard from many people, atheists, agnostics, other Christians, Jews, Muslims and
everything else(not literally) exactly how wrong my beliefs are.
But, you do understand the difference between geology and computer science? Or electronics and let's say biology?
And secondly, I do not have to deny all science. What I do is think for myself. I love science and think it's great but I believe even scientists can be wrong. So I use my thinking cap alright? Scientific theories come and go. Even scientists don't always agree between themselves. There is a scientific consensus but it would be really boring if we all just went along with the current consensus don't you think? Maybe if Copernicus just went along with the consensus; then we'd still think the earth was the center of the universe? What I'm saying is that someone has to question the consensus.
BTW, if you read the Genesis account carefully you'll find it doesn't mention when the planet was actually made. The "earth" of Genesis is actually the land; in other words the continents. So the mountains can be much older than many creationists believe for all I know. However evidence shows that the mountains were once under the oceans. So this actually supports the Genesis account which describes the land as being underwater at the beginning in Genesis 1:9.
Interesting place. Do you live in Utah? I want to research this specific canyon a little bit more before answering you.
