Are aliens helping us to evolve further in technology and creation?
Highly unlikely, any aliens advanced enough to A) be aware that we even exist and B) travel or otherwise communicate with us would be so far ahead of us technologically that we'd be little more than a curiosity at best.
At our current understanding we're already at the brink of vat grown organs, artificial wombs, genetic modifications/enhancements, neural integrated prosthesis, etc.
There is no logical expectation that an advanced alien race would not be able to create their own beings to fill whatever role they might be preparing Humans for.
Neither would they have any use for any technology we might be expected to invent for some time and why they would expect any technology from us that they could not create themselves is unexplained.
In short there is no reason that they would even if they could.
