Noahs Ark... Is it really true?

I tell you now, the great flood some say we had, I don't believe it happened... This apperently killed off all the dinosoars as well... Now lets talk about Noahs Ark. Apperently one guy was suposed to get together 2 of each animal on the planet and put them onto this huge boat to save the species so when the flood is over with, they can carry on and breed into the future You really think anyone would come close to an aligator, lion, cougar, giraffe, hippos, elephants etc.... without getting eaten? Even if you had like 5 people collecting one animal at a time, you think they were actually able???? haha I don't think so. How many different species did they say were collected.. Not sure..
