Thank you for your reply, Alia Atreides, and welcome to the fray.
We could argue that the Lord's work is magic, yes, ...
Have you also considered the possibility that Satan himself left false "evidence" for foolish pseudo-scientists to dig up and, without proper knowledge of the bible, fall victim to and believe in?
This is, of course, your prerogative. This is America and you are free to believe what you want.
Maybe your meanders and cross canyons, etc. were formed by more than just the flood. The flood may very well have formed the initial formation of the Grand Canyon, and subsequent assaults of God's wrath carved the remaining portions into existence (such as from meteorites or comets, which are even mentioned in the bible).
Again, you are free to believe what you want, and this means you can make up new ideas to explain the evidence as you go along, if that is what you want to do. Brainstorming ideas is fun.
Science takes ideas a step further though. Not only do you need to explain
all of the evidence, but you have to test it against the objective evidence of reality. Sadly, for me, I note that impact craters, to the best of my knowledge, do not look at all like any canyon (usually being round or elliptical), so that explanation does not satisfy me any more than previous explanations of how catastrophic flood formations are involved.
People have claimed that the Grand Canyon is evidence of a great flood, and all I have asked for, is for someone to show me the evidence that must involve a flood to explain it.
... but that's not necessary. The bible clearly indicates that a worldwide flood ravaged the Earth. This we know.
We know that this is one of the things that is clearly indicated in the bible.
The problem is whether the Grand Canyon can be used to scientifically show that this was actually so, and so far I have not seen any argument that shows scientific evidence of catastrophic floods of biblical proportions.
Enjoy.
Note: my time is limited, so I only choose threads of particular interest to me and I cannot guarantee a reply to all responses (particularly if they do not discuss the issue/s), and I expect other people to do the same. Thank you for your consideration.
