Hey Charles, this is bdw from long ago.
Anyway, have you ever checked out the www.thunderbolts.info
Well worth checking out, they claim that electricity/magnetism is ignored way too much in astronomy. One of their main claims is that "impacts" are NOT from meteors, but are actually huge (and obviously, really, really huge) lightning strikes between planetary bodies. They make a very convincing case that the grand canyon is a lightning strike, as well as the big canyon on Mars.
These guys are not kooks, and some of them specialize in ancient mythology being inspired by astronomical "events" that were seen in the sky just a few thousand years ago.
Just a suggestion. I have no way of knowing if you would like any of this stuff.
Check out this Grand Canyon article if you feel inclined: (Wal Thornhill has his own webpage)http://www.holoscience.com/views/view_mars.htm
A picture is worth a thousand words.
