Could E.T. have influenced religion?

as for the reason you gave, sure it is all perfectly viable, and a thousand times more likely it happened in a way you suggested than by aliens cutting it with a big fat laser. but it's still not concrete 'this IS how it happened'.

You appear to want science to give you a final answer on this issue. And very likely it can give as final answer as one can be given. The problem is that you are looking for an answer that can't be given to you with the rather sparse information that you've provided (or not). The Nazca plain is a very remote region, and because of this fact, there is very little geologic information readily available without doing a more extensive search. What is not in question is the fact that the Nazca plain is a fluvial fan/apron. What is not in question is that erosion in arid regions that have undergone tectonic uplit often develop exactly the kinds of landscapes you see in the photos about which you queried.

then it's just a mystery isnt it? it's not wrong to question a mystery is it?

if i cant get an answer then that's fine. don't really see what else is to say about it. i'm sure people can come to their own conclusions and have their own thoughts. hence the point of the post
