According to the mythology Ramayan happened first and then comes mahabharat.
There are some evidence that does suggest the happening of a great war about 3500 years ago which could be the origin of the epic of Mahabharat but no historical or archeological evidence is available for Ramayan.
Someone who experienced it and was there when it happened
I think that he sent missionaries to other kingdoms.
