if you got a letter from a friend, the time stamp is 1800 bc, how old are you now? i don't know for sure. but i am sure that you knew your friend at/before 1800 bc. you are the earth, your friend is the far star, light is the letter. gravity is the mailman. thoughts?
I think you're trolling. The only alternative is that you're too stupid to even breathe without supervision. And you can't honestly be that stupid, therefore: trolling.
