Clarify what you mean by "evolved".
If earth had no carbon dioxide then no plants (or animals) would have ever evolved because they all need it for respiration to take place.
Humans and everything else May have evolved to be alot taller things would be alot lighter the earth wouldn't be so compacted alot of things would change

the earth would be destroyed
the earth would die
Earth would stay the same
we would be dead
you would be melted
if it isn't born yet or evolved then it will die.
earth would no longer exist
No
Earth would stay the same
