The Bible claims that Noah lived 350 years after the flood, dying at the age of 950. This is in Genesis 9:29. I would think that over the course of 350 years, someone would have found a use for the technology he developed, which would be quite advanced for his time. He could have helped rebuild civilization, since he was obviously quite spry at 600, building the largest object ever made up until that time and keeping it afloat while taking care of thousands of animals. Had Noah existed, he would have been able to greatly advance technology, but for some reason he did not, choosing instead to leave not a scrap of evidence of his own existence besides a story so absurd that any thinking person should be able to discount it.

It isn't for the kids who are taught these things by people who they assume aren't lying. Disbelief is often more of a choice than belief.
