I know, don't try to make any sense of the ending, it's just complete utter shit.
All your choices from ME1& ME2 are useless because of those endings. I wanted to see what happened to all the different races after the war and what became of galactic civilization but nooo Bioware had to fuck up the end of a trilogy.
Also why the hell where my squadmates, who were with me when i was running towards that lightbeam, suddenly transported to the normandy at the end?
