Water is made of 90% oxygen so how could it be that there was no oxygen in early earth?
Huh?

Where are you getting this nonsense?
First, water is H
2O.
Two Hydrogen atoms and one Oxygen atom.
But don't try to breath water, it don't work well for most humans.
The issue relative to the evolution of life on earth though is the availability of free oxygen in the atmosphere.
What I think you may be referring to is the amount of dissolved oxygen in water.
BUT...that still has nothing to do with the topic.
Anyone so limited that they can only spell a word one way is severely handicapped!
