The timeline we've been watching is the one in which he went back. Old Caps been here the whole time.
That's a legit answer too. The only issue being that Captain America would have to assume that his return wasn't going to create a butterfly effect that changes everything. Or maybe he just didn't give a shyt what he was going to change, said, "fukk it, I'm going back", and then just got lucky that nothing much changed and he was still able to show up at the same spot to see everyone off.
Jokers like that always find their mark immediately in any new situation.Ant man basically became dude from Guardians for him
Nah, they were definitely definitely dead.So I think they all got banished to the same realm and weren’t dead but weren’t alive in this atmosphere.
Remember that Doctor Strange knew what the plan was even before he died. So the second Hulk snapped them all back to life, he would have gotten to work instantly. First he uses the portals to gather all the sorcerers and then they all use portals to get all the superheros assembled. There was a pretty long time between Thor's snap and when they came into the picture (the initial aftermath, and then the destruction of the building, all that time Thanos spent just waiting in place, then the whole Thor/Cap/IronMan/Thanos battle). That's more enough time for hypercompetent sorcerers with a plan already in place to run around and grab everyone.
