But my point is that they didn`t even try to follow the things that couldn`t be changed.Kirk wasn`t even in the academy when Pike was doing his first voyages of discovery during the maiden voyages of the Constellation class star ship Enterprise.Its as though they moved ALL the characters back in time as far as their own births.I didn`t buy it.What about Pavel Chekhov?He would have been a preteen at this time.
I haven’t seen the movie yet so I can’t really discuss it with any real knowledge but from what I have been reading all the inconsistencies you are talking about is on purpose.
This new reboot doesn’t necessarily follow the Star Trek TOS canon.
Or, instead of looking at it as moving all the characters back in time, you can look at it as moving the date of the construction of the Enterprise forward in time and just chalk it up to the butterfly effect, and deduce that Pike did his voyages (including the one to Talos IV) at the same time as the original, but in a different ship. Heck, if you want to get REALLY technical, you could even say that the destruction of Kirk’s dad’s ship was responsible for messing up Starfleet’s ship-building schedule.
And, IIRC, Chekov was 24/25 in the original series, and 17 in the movie, so that gave a 7-year age gap that would also seem about right for the rest of the characters (Kirk was in his early to mid 30’s in the series, mid to late 20’s in the movie, everyone else looked about right in relation to each other).
