How is it that humanity became as strong as the council races in like three decades? Stolen prothean tech? Also, even if the council was killed in the last game how is it possible they didnt send replacements? Are you telling me the Asari, Turian, and Salarians entire military was at the citadel?
Because I don't know if you've noticed yet, but humans tend to expand and grow remarkably fast.
Look at our own history, in less then a hundred years, we've gone from single shot rifles, extremely basic communication, planes made out of paper and sticks that could barely hold one person and a gun, and honestly not even knowing that there was more then five planets in our Solar System to talking about the fact there may be a Multiverse of sorts, having planes that can carry 300-500 people at a time, the internet, really I could go on here.
Its not really that hard to think that Humanity could grow so fast in the ME universe with everything they have gained, they have the ability to study Prothean Tech, and even if that gets used up, we now have decent to good ties with the Galactic Community, which would allow us to advance our sciences by several hundred years if not more, and with this wealth of new knowledge, its not hard to think of humanity growing so quickly at all.
