First Class changes Charles' age when he and Erik first met (he's in his early 20s in FC), therefore retconning the mention in X-Men of Charles being 17 at the time he and Erik met.
Although the previous mention of Charles' age being 17 when he met Erik still exists in X-Men, it is overridden by the retroactive continuity of First Class.
Please stop making up excuses as you go along.
I can understand if the producers / writers did a George Lucas and re-released the first Xmen films with selected parts re-imagined
but they haven't.
It's either terrible writing for First Class or the first xmens films are from a different filmverse. I suspect its the former.
