40 days and 40 nights...

Same as Noah on the ark....

God saved him and his family (and the animals) and wiped out all the others who had turned to evil ways in a rebirth or 2nd start for mankind...

The island as a potential 2nd Garden of Eden?

One "Adam and Eve" (found in the caves) failed somehow....

Another "beginning" or test of mankind to see if it will turn to "right" or "wrong" given another chance?

i've thought about noah and the 40 days, but i don't think it's right. it's definitely a good theory, but just one i don't agree with. not sure why- it just doesn't feel right to me, i guess.
