Mind blowing question

if theoretically both time travel and heaven was real if you went back 50 million years in the past and died. What/ who would be in heaven would you be alone and would you have to wait 50 million years for people to start showing up. and when do people start showing up When we evolve to human form? when we start speaking? when jesus comes? and then youd have an impossible language barrier till eventually modern people show up and by then youd have gone insane weird
