Could E.T. have influenced religion?

That being said, sug, it's a ridiculous supposition. I've watched several documentaries on it as well, and read books, and I find it demeaning to the human race to think we needed outside help.

The human brain is an astonishingly clever and creative thing. Aliens aren't needed.

so humans can carve a mountain in half? and leave no trace of rubble or carving yet mountains around it are all perfectly normal? please something other than humans did that.

Amongst many plausible geological agents - Deposition followed by tectonic uplift and erosion. Mature Mountain range erode, the debris fill in low lying areas until they buries the mountains up to their shoulders. The whole area takes on appearence of a flat plain with isolated peaks poking out. Then entire area experience another pulse of uplift, tilting the plains and accelerating local erosion, causing streams to incise into the flat plains, cutting them into isolated flat topped buttes and exhuming the buried lower parts of the original mountains. The result is an area with real sharp rigged and peaked mountains, interspersed with flat top buttes that look like mountains with their top chopped off.

This sort of formation is quite common, especially in the US. You might drive along the front of the Rockie mountains to the west of Denver and see a dozen of these seemly truncated mountains standing in sharp contrast to the appearently prestine peaks of the Rockies near by. This wasn't made into its current form in 5000 or 500,000 years. The whole process that got them to their current shape took at least 4-5 million years.

BTW, You won't find big piles of rubble looking about the flat topped buttes near Boulder, CO, either. The rubble from these appearent cutting of the mountains along the front of the Rockies in half are mostly on bottom of the Gulf of Mexico. Moved there by the Mississippi. Some of it now makes up the land that New Orlean sits on. Some of it is on the floor of the Atlantic, having been blown there as wind blown debris. I certain doubt those whose instinct is to attribute everything they can't explain to god or ET could possibly have the wherewithall to eventually discover on their own how normal processes can produce results that seems defy normal expectation.
