Where do you get this satan from? Sure the OT speaks of people who are 'hassatan' meaning, the satan, not a proper name, rather it means a person who blocks, impedes, is an adversary, somebody who stands in the way. So it's something that blacks the way to God, be it a person or a personal weakness.
The first hint of this impeder is when it stops a donkey. Sure has come a long way to now be building flying saucers and this satan may also be able to create aliens.
If any of the UFOs are really from another system might they just be one more wonder in the vastness of the universe? Does it always have to be about us being availed by satan no less. Satan started off as something non-specific and certainly not a being with a proper name, but today this thing is every bit the equal of God, at least in the minds of believers.
Imagine the impotence of a God who is constantly shadowed by an evil presence who offers no more than an endless promissory note that one day He will to do away with satan and evil. What if satan was really just the human nature we wont admit to?
As for 'inter-dimensional', who says that such a state exists? If it did you could be pretty certain that anything from that dimension couldn't exist in this dimension and visa versa. Those dimensions would be incompatible otherwise they wouldn't exist separately and they most likely don't exist.
There may be beings in this universe far closer to God than us.
