How do scientist know that there was no oxygen present during the Archean Era?

iron oxides turn red in the presence of oxygen and the rocks found in this era were not red.

They actually did find oxygen during this time frame but the Earth was too hot to have life at that time.

They found fossils of organisms that made energy without the use of oxygen.

The organisms were whiped out due to comets and asteroid hitting Earth that life ceased to exist during the Archean Era.
