Cute.
First of all, Ken Ham is not God, whatever he may think.
Secondly, I don't see anything in God's Word that says aliens are doomed to hell.
Come to think of it, I don't recall seeing anything at all about aliens...
Okay, here we go...
The universe definitely had a beginning. Since nothing can come from nothing, there had to be a source....or Source, which we call "God".
God created the entire universe, not just this one tiny solar system, and it seems likely that He peopled it with life.
Now, we have no way of knowing this, so I am assuming, here.
If I'm right, then surely a loving God would not focus on this one planet and leave all the rest of His creation behind.
My personal belief is that every single planet that boasts intelligent life has also had its visit from the Lord Jesus Christ...in whatever form that life might take.
However, I digress.
To answer your question, Ken Ham has no idea whether or not aliens even exist, and yet he is willing to consign them to hell.
Doesn't say much for his Christianity, does it?
