I think that you are thinking of something different. In the past, there used to be higher levels of oxygen in the atmosphere. This meant that giant insects could exist (and insects were on land before other animals, so they could dominate). This is because insects don't have lungs, but rather have small tubes that ramify throughout their body that are open to the air, air flows into them like normal. With a high concentration of oxygen in the atmosphere, that meant that they could grow big, with current levels of oxygen, there wasn't enough oxygen left in the air that flowed through those tubes to feed the needs of the whole body or the deep tissues. So they evovled to become smaller.

Mmmm sounds nice.. So ants could roam thw world?
Maybe spiders? Men that would be pretty weird if the would roam the world !

It all could happen dude !

They roam the world now...

Yes only in your thought the roam now !
But if the roam again.. dawm.. how strong do the have to be?

We can kill them easily with our rockets and stuff

How does that work? I'm sure theres enough oxygen around us and unless they were hundreds of miles high so they're heads were in the upper atmosphere they could breathe.

I agree with Jack.. i mean the could live here easily

Why the should? Maybe there were animals that didnt need oxygen.. maybe that had another kind of oxygen.. maybe the could live on koolfstofdyxide?
