First, so surprising you posed this question! Good learner. Second, try to answer it. Both words have the negative meaning to negate objects. However, they have different speeches. “没”usually serves as an adverb to negate the (notional) verb such as "没有 not have" or "没做- not do”. "不" serves as an adverb to negate the adjective behind it such as "不对- not correct" or "不好not good". Moreover, "不" can also negate the copula "be" such "不是- be not.

没sometimes means things didn't exist 不sometimes means the opposite meanings of the thing and negative things or to be against
