Actually, I think from a point a view of mathematics and probability this makes an OUTSTANDING point.
An earlier post I made about legitimate scientists discussing "spacetime bubbles" etc as a hypothetical means of faster-than-light travel, and the IMMENSE number of probable other intelligent civilizations, and the immense AGE of the universe, would to me say it is close to certain that some extremely advanced alien civilization is very likely to have come up with means of getting around the FTL "speed limit" and other limitations. Time travel I am a bit sketchier on. It seems possible to go forward in time, but not back. I dont think there are even any wild hypothetical suggestions how that might be done, only forward.
Actually mathematics and science (from what ive learned) has shown that the phsyical "guidelines" needed to sustain life that can evolve like ours requires a special type of planet, within a special distance from its sun, with a special axis and many other things, like special amounts of substances on the planet. out of the millions and billions of planets only a few have been calculated as "able to sustain life"
weve just started finding traces of water throughout the universe, it will be many years if at all that we find "life", regardless of its intelligence or complexity.
on a slightly different topic. one astrophysicist theorized in his paper earlier this year that our universe is INSIDE of a blackhole INSIDE of another universe. that every black hole has the ability to produce a universe inside of it, each with different laws of physics. some may be unstable, some [like ours] grow. now THAT would destroy the meaning of life

ill look for the link
also, backwards time travel IS possible. According to einsteins calculations, you need a cylinder of INFINTE length, meaning it stretchs from one end of the physical universe to the other, there is no beginning and no end to the cylinder. When the cylinder begins spinning (at fast speeds I believe) it begins to warp space-time with it, and actually can send time BACKWARDS. albeit, we will find little green alien men LONG before an infinitely long cylinder...
like i said about mashing conspiracy theories together. even if there was intelligent life out there....are they REALLY working with the US government in secret? I highly doubt it. And DMT? That fits in no where.... if heaven did exist, the government would not have a single goddamn clue to its existance.... or else God would have failed being the almighty deity....
the puzzle pieces just dont fit for me
on a side note: for anyone claiming aliens are probably living in "other dimensions" i HIGHLY doubt that will ever be found to be true. physicists that DO believe there are more than 4 space-time dimensions (or more than 3 spacial dimensions) theorize that the reason WE cannot interact with these dimensions, is because [there are energy orbs surrounding] the particles that make up everything we see and touch, and prevent these particles from leaking into the other dimensions. meaning most of the matter in our universe is stuck in 3 dimensions of space, and it would be IMPOSSIBLE for life to evolve in "another dimension" its just not realistic. Proof that other dimensions exist, proves that and only that.
if DMT in fact teleported you to another dimension, or let you "see" the other dimensions, everything in that dimension including the creatures would have to be made up of some crazy unheard of particle or something.
i only have a little astronomy/physics education under my belt so id love for someone to prove me wrong! no really i would, i love learning new things, even if it means im wrong.
