As the earth cooled, water vapour in the atmosphere condensed to a liquid (water) and fell to the earth as rain the make the oceans.
It condensed and formed water vapour.

No! Stromatolites converted the toxic atmosphere into a breathable one.
a. There would be no volcanic eruptions. b. Water vapor would never have condensed to form the oceans. c. The atmosphere would contain no carbon dioxide. d. The second atmosphere would never have formed.

What happened to all the water vapour in the early atmosphere
reacted out with oxygen as oxygen levels rose.
Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.
Not a lot! Early life transformed the atmosphere; removing much of the carbon dioxide, so without life Earth would probably have an atmosphere and environment like Venus.
No. The early Earth's atmosphere contained a lot of ammonia, for example.
