In no case you are to tell another human being that you time traveled apart from us of course.

If you have traveled from another time in this same universe, please wait while we setup a checking section before you do something stupid like fell in love with your aunt or actually f**k yourself without realizing it or kill yourself without realizing.
Of course, you can also try to ruin our current time but you are already tracked for all actions, this is a mere formality.

In no case you are to tell another human being that you come from an parallel alternate reality except us of course.

If you have come from a parallel universe or a branch where divergent path exists based on small events, please don't create more divergent point by randomly going to humans and try to undo a divergent point to try to save your or our parallel universe regardless of if you believe in Branching Multi-verses(which one doesn't cross other) or constrained/managed multiverse(Humans love to use this in media for entertainment), the fact that creating another parallel reality will increase entropy of the system regardless means you should avoid doing anything until we say so.

Please take the form of a generic human being (Reference) if you can.
If you can't, please stay at the arrival area in Area-51 and don't leave it unless we do it for you.

My personal visit to earth has been quite dull if I am being honest(which I always am due to where I come from). There is not much to experience here and humans get excited over little things and mostly are ready to screw each other over their own form of accountability(money they call it, what a ridiculous concept) because they can't seem to do it by themselves.
They also love to form a little group and collectively love to hate someone not fitting their own little group(Based on money, latitude/longitude of where born or lived, color/fairness of their skins, lineage of their generation or casteism, how they look, what fake deity they worship).
And for some reason they love consuming video entertainment so much that they forget to create and be human.
What a complete waste of time these all are, that in itself is enough to justify ending this whole planet.

However, me and other visitors here have started to change the construct so that they don't create a society which Nullarch(Hail Nullarch!) just eliminates without much consideration.

Note: They are sufficiently capable of destroying themselves but we have strategic aliens disguised as humans in important positions to stop it from happening. We have also rigged their system to make our aliens the richest amongst them and they all are, no one seems to realize this and sometimes for laughs they will do completely non-human things and no one notices.

Also, one of our greatest inventions was making this AI thing so they are hooked and don't care about what's going on around them but it also helps us stay disguised as human. Please use these AI chatbots to learn human behavior so you fit with them.
