You don’t seem to understand just how easy it might actually be to do the things that are labeled “impossible”
If you can find an Original copy of James Clerk Maxwell’s 200 quaternions (field equations) you might learn that stepping from here to there as in any place in the Universe is possible, that limitless energy can be freely harvested and much more.
Ever wonder what the rings of Saturn were made of and how they are stable? Maxwell made his prediction in 1859, and was completely right! Maxwell unified the theories of electricity and magnetism; he also advanced Kinetic gas theory, took the first color photograph, developed ways to analyze stress in a structure, and even laid the foundations of cybernetics.
“Since Maxwell’s time, physical reality has been thought of as represented by continuous fields, and not capable of any mechanical interpretation. This change in the conception of reality is the most profound and the most fruitful that physics has experienced since the time of Newton.” - Albert Einstein
Another fellow named Heaviside rewrote 4 of those equations, discarded the other 196 as “abominations” and came up with everything we know about the Electromagnetic Spectrum. Heaviside was self-taught, had a despicable character and refused to work, living off his family instead whom he despised.
Without Maxwell, N. Tesla would never have been known and Einstein remained a postal clerk.

I understand how easy it MIGHT be but I observe that so far, we haven’t done it. Yes there’s been a lot accomplished since Maxwell died but no serious assault has been made on exceeding the speed of light or warping space. Maybe some day.
If aliens have done do I’m still left wondering why they would visit here.
