Question ☝🤓

Okay so mods I'm REALLY sorry if this question was already asked here, I tried to google it but I had no luck so far and I'm really curious about this.

So a while ago I started watching Transformers Animated and in the very first episode the bots watch a clip (an historical video for them ig) of G1 Transformers and the war between Autobots and Decepticons. It is also said that Ratchet was in that war and all the others (this universes Bumblebee, Bulkhead and even Optimus himself) weren't there.

So my question, or rather questions are: Is TFA tied to G1 continuity in any way? Is TFA Optimus a descendant of G1 Optimus? Is TFA Megatron (and all the other Decepticons) the G1 Megatron who..idk..travelled through time? Or is TFA just a universe on it's own?

Like, maybe the answer should be obvious to me but it's not (and maybe I'm just looking TOO DEEP into it 💀). Sorry if the questions are dumb (and repeated), ik that Transformers continuities can be a bit messy. Anyways, thanks in advance and sorry if this sounds confusing.

P.S. : There might be some spelling mistakes. English is not my native tongue and I don't have auto-correct.
