A person without a bias (i.e., a clear and open mind) would see that there simply isn't enough evidence to draw any conclusions...yet.
That’s been my point, it’s my belief that alien life exists in abundance, have they been to Earth, I have no idea and probably won’t find out in my lifetime.
It’s a belief that can’t be proven and doesn’t affect my Christian beliefs and people can agree or disagree that’s fine and I don’t really care.
The problem is that the term "yet" represents an open-ended commitment that can only end when incontrovertible evidence of intelligent life outside the earth is found. The universe is so vast that there's no way every corner of it can possibly be searched ... so "yet" goes in (forever, in theory) unless and until something is found.
On the other hand, there's a perfectly reasonable bias that has nothing to do with faith and everything to do with scientific/mathematical realities. The longer I look for something without finding it, the less likely it would seem that it exists at all. That's not a matter of faith. It's a matter of empirical evidence.
