just random question wont be to long but ok i have full understand of what we know about the courier but we still know so little and nobody knows his past or past him besides uylsses and his noliage is limited soo i like to pretend that the Lone Wanderer some how came to the divide and founded the town and got shot and etc and fogot his father and etc but do you think this is even plossiable?

No it isn't possible. The divide was already a town that the NCR controled when the Courier came along and delivered the package that destroyed the town and created the Divide, right around the same time the Lone Wanderer was leaving Vault 101. The devs of New Vegas have said many times that the Courier doesn't have amnesia.

The Courier is not the Lone Wanderer.

What Styles said, but I also felt that this was all but confirmed in the vanilla game. I'm pretty sure that the Lone Wanderer would be more knowledgeable about topics like the western Brotherhood of Steel than the Courier is, at the very least he or she wouldn't believe that they shoot lasers out of their eyes.
