Haven't encountered any solid proof of existence.
Not convinced of visitation.
No personal encounters..
Likely that other lifeforms exist, some "intelligent".
I'm not religious.
Lack of mass contact events presumes that an alien species exists, is capable of traversing the vastness of the galaxy (at least), and, in that vastness, somehow not only located Earth, but found it of enough interest to investigate with any more resource than an automated probe.
That is one boggling large ask.
As to a space elevator. We have yet to develope a material strong enough and ligh weight enough with which to construct such a device..
Furthermore, if we could develope such a material, it might be more efficient, and economically feasible to use such a material for the construction of "Vaccuum Cell" airships which would allow access to space without the need for propulsion, at least until maneuvering in the space environment is desired.
The current (pardon the pun) problem with space-based solar power systems centeres on how to safely transmit the energy they collect back to Earth where it is needed.
