We also don't know how much time passed from his "death" to the attack on Konoha.

If his height is the issue for some, when we see Kakashi and the others during the attack on Konoha, they appear to be the same height as Naruto is currently. Obito would be of similar height.

If power is the issue, he was only able to do what he did because of an overpowered mangekyou ability. And he still did not measure up to Minato in any way. He challenged Minato, but he was overconfident and got his ass royally kicked and was forced to retreat. Even with an time-space ninjutsu superior to Minato's, he lacked Minato's experience.

I'm sure if you are patient, we will get some flashbacks that show what happened and answer most of the questions. Kakashi will most likely ask Obito many of these questions himself.
I dunno where you put your eyes, but during the chuunin exams, kakashi and crew were tiny, the size of konohamaru at the start of the show.
During kakashi gaiden, they were the size of naruto/sasuke during their battle of the valley of the end.
And why is this even being debated, it has already been established that kakashi became chuunin at age 6 and jounin at age 13 (nearly the same as itachi), also the fact that he is 26 at the start of the show means obito died at 13 and the naruto's birth was 1 year later.
