It's not at all that simple..

Sometimes it is as simple as that. This earth is big enough to have giant lizards roaming it then it's big enough to have giant humans walking it. Those 300ft trees aren't there for a show. You want to believe in evolution, then this is the real evolution. Humans evolving according to their needs over long long period of times.

lol
NOBODY try.
this pointless guy is pointless... ahmedjunior knos lool
itsa waste of time he will go in circles over and over and over as if he has never been on a merry go round........if u havent then try it..it aint fun...

Well, it's not that simple in this case.
And this has nothing to do with evolution, except for the part that muslims believe humans shrinked somehow troughout history..
Dinousaurs and giant trees are designed to be that big, a human being is not. Unless Adam was anatomically significantly different from the modern day human he can't have been 90 feet tall. So technically, if you believe Adam was 60 cubits tall, you must also acknowledge evolution, God led evolution if you will.

Can i have the pleasure to say:

?

hold on let em bang heads a bit. its sorta fun watching ...gets u dizzy but still......lol

Even people who are 7/8 feet tall have real trouble with back and joint pains because of the increased pressure. The materials are the same as in an average size person but would have to cope with much greater forces, as a result of leverage on long limbs and compression of the spine and joints.

The largest dinosaur was roughly 75 feet long and 40 feet tall, weighing 80 tons.
A bipedal man who was bigger than this would probably crush his own bones under the weight or have limbs so heavy he could hardly move.

Calculations on animal size

Hush! I was having a good vision of Adam riding on the back of a Brontosaurus like it was a pony, now youve gone and spoiled it.

And Actually I think you'll find that if you measure Barney the dinosaur, he is only about 7 ft tall in his suit, and he sings and dances and dosnt suffer from this "back pain" despite having a man inside the suit. So that totally blows your point out of the water.

I'm sure when he was a boy he rode them like ponies

Barney and Denver should form some sort of prehistoric Steps and go on tour.
