Just because that last drop happened to show me what we had done, this doesn’t mean that the last drop carried out all those great achievements. :)

Correction: I wrote this sentence below *a* few weeks ago, but I'm not *exactly sure if* I could understand *it because* in this sentence, does *"didn't" really* need *to be* here? "Just because the last drop made me see what we *had* done by *making the result visible* by chance, it doesn’t mean that the last drop didn’t carry out all those great achievements." What I want to say in this sentence, the last drop isn't special but every *drop* from the first *one have* the same value.Could you tell my the correct form or recommend one, please? You can express this sentiment either way, with or without "didn't". Without it, *carry* would need to be in the past, i.e.: "...the last drop carried out all those great achievements."
