Just one?

I've been playing this game on and off for like 2 years and I finally use the human race hearing how flexible they are... And then I find out I can't pick the same state with human greater adaptability..how come every other race can choose +2 to a stat through enhancements but humans can't? Is it the fact they can choose any stat?

This.

Most people can make use of at least two stats though.

The fact that they are the only ones that can choose racial +1 int, +1 wis and +1 cha more than makes up for it on casters. On melee, human adaptability is ridiculously strong, especially if your class has haste boost (fighter or rogue for instance).

Humans are already the best race as long as you're not making a one-dimensional character for all classes, a balanced character that can take 3+ roles are always better off being human. Humans don't need a buff.
