The Ark was found . In an article i read ages ago. It was
found.. and the dimensions were all correct to the biblical info.
Somemore it was found on a mountain. Explain THAT! I dun think
Dinos were on board.. i think they were long extinct before Noah
was set on this planet
It is never found. If I am not wrong the mountain something u
said r NATURAL and not man made.
Mathmatically it is impossible the ship with the size described in
the bible can hold a pair of animals of the whole world inclusive
of food and drink. In fact tat r studies tat showed just containing
the beetles it need 10 times the size of the ship as prescribed in
the bible. Furthermore u need to remember buoyancy and tat there
have to be some empty space in the ship in order for it to
float.
genesis 6:15
15 This is how you are to build
it: The ark is to be 450 feet long, 75 feet wide and 45 feet
high.
nowsaday tis is consider a medium size ship 
Noah might have just brought 1 pair of horse (ancestors of all
pony, donkey, horses), 1 pair of dog (ancestors of all wolves,
dogs, foxes, dingos) and so on.
The Ark didn't have to hold so many animals.
If u follow the bible u will realise tat it only reach our time
in about 5000 years. Tis time period is too short for evolution to
take place, if u believe in it
Noah doesn't have to bring mature dinosaurs in, he can bring in
the eggs or babies
genesis 7:15
Pairs of all creatures that have
the breath of life in them came to Noah and entered the
ark.
Unless eggs can walk I think the idea of eggs contradict the idea
from the bible. Even if they bring children of animals in they
still have to eat and drink a lot in 40 days
