Time machines from the future? Aliens using earth as skipping stone airport? Advisory’s? What’s your best theory?

Title says it all I personally think it’s us from the future and the reason why they don’t want to fully interact with us is the butterfly effect? 🦋 🌬️ 🌊

What’s your best theory you can think of?

SadGuru mentions that aliens are using our earth as a skipping stone airport and use water as fuel or something or maybe they have a base under the water?

He thinks they have been doing this for a very long time it’s only recently that our technology has advanced enough to actually somewhat track them?

So what do you all think?
