I don't know whether my question is relevant to the subject.But i want to use this forum to clear my doubt?
After big bang theory,the world/earth met with a heavy rainfall,at that time there was no vegetation,Now we are saying 33% of total area should be rain forest to bring rainfall.(we know the fact how rain forest is working in bringing rain).How the first rainfall happened without a single tree?
Eagerly waiting for the answer.
with warm regards
