And whilst being equally inept at allowing themselves to be seen and recorded... they have also managed to pilot their rocket ships between the large amount of space junk which is now orbiting the earth....

Not that hard, there's an awful lot of space there...

The Tuesday hypothesis of UFOs, that sightings are a mess of fraud, natural phenomena, psychological suggestion and the like, predicts:

(1) No physical artefacts of non-earth origin will be discovered.
(2) No alien life forms will be discovered.
(3) The laws of conservation of mass and energy will not be found to be violated.
(4) Inconsistency between sightings will be noted.

I further suggest that any theory of alien origin which allows these aliens to be so inept as to show their existence through the many sightings, precludes their being to hide from us without discovering (1) or (2).

And whilst being equally inept at allowing themselves to be seen and recorded... they have also managed to pilot their rocket ships between the large amount of space junk which is now orbiting the earth....

..the alternative theory relies on the pilots of ufo being alternative versions of us, and are visiting different alternative realities....

I've no idea what you mean, but please let us know what your theory predicts will happen.
