The beginning of time

As far as the MCU is concerned, if the Infinity War is the culmination of 3 Phases, where did it all start? We might expect that the first Iron Man film (2008) was the one responsible. It isn’t so.
As far as the MCU is concerned, Iron Man was the winning bet which made it all happen. If that one movie wasn’t successful, then we wouldn’t even have guessed what the future held for us. But Iron Man was much appreciated by both fans and critics alike.
Only afterwards, with Iron Man 2, Kevin Feige started planning the MCU, with the Tesseract being the central piece of the first phase. Furthermore, Feige also said that they don’t usually plan everything to perfection – even at this moment, the MCU is just sketched in broad strokes. Of course we know that everything leads to the Infinity War – but what happens until then it is still somewhat of a mystery (Civil War and Doctor Strange aren’t that mysterious).
