I think this may be the same thing your friend was talking about but who knows, this isn't the first time "Christian archaeologists" (lol) have claimed to have found the Ark.
Maybe it really is a boat, alright, cool. That still proves nothing other than they found a really old boat! Sorry, but science proves this myth wrong. First off, a world wide flood is not possible (there just isn't enough water on our planet), and well, we don't need to get into the details about fitting millions of animals/insects onto a boat (over 100 million species on our planet). Shit, a 4 year old could tell you that's bullshit. You would need at the very least two of each species (to reproduce later), hundreds of thousands of tons of food to feed the millions of species, someway of keeping certain species away from the others, climate control, etc. There are just so many problems with this story. Anyone who honestly believes in this shit is either A). A complete wackjob, B). Stupid as fuck or C). Mentally retarted.
