18,000 species changed into 15 million in a few years 0_0, if you believe that is possible, why do you say evolution is impossible? I thought that creation arguements say evolution is supposed to be degenerate, not this diverse???
Also, How many plants do you know that would last for a month under water without dying... We've got a lot of vegetation all over the earth.... Seems that once they got off the ship, there wouldn't be anything for 36,000 animals and a few humans to eat :P
