Which does nothing to prove this is the result of a cycle.
What's this have to do with something that's cyclical? If it happened before and it's a cycle, it'll happen again. Otherwise, it's not a cycle, is it?Without knowing the COMPLETE life cycle of the planet, it is impossible to know at what stage of it we exist.
No, we don't know that at all. Albert Einstein once said, "If the facts don't fit the theory, change the facts." Taken out of context -- as I just did -- this would seem to suggest quite a bit of dishonesty on his part. Clearly, this debunks his theories. The people of Hiroshima and Nagasaki will be happy to know that they were attacked by a wild theory that is now debunked.So with that thought in mind, how are the scientists to know that their data is correct? Besides which, we now know that many of them LIED.
