Questions: Religion & Spirituality

So I had a discussion with a Scientologist today. Apparently they believe that the great space alien Xenu came to earth 75 million years ago, bringing billions of humans with him, only for Xenu to go rogue and nuke the earth to oblivion with hydrogan bombs (in 75,000,000BC) wiping out the humans and dinosaurs. This is known as 'Incident II' to Scientologists. And they believe Xenu is coming back to do the same again any day now?

Is anyone familiar with this? What are your thoughts?

If you disagree, tell whether you think they are weaker or equal in strength.

I think most think Holy Ghost filled people are spiritual stronger and I agree with him. I think it is pretty obvious that God's work is greater than Satan's work, both inwardly and outwardly.

Please share your thoughts! I will like to know why you think many do or don't agree with you.

I am not asking which group suffers the most but which group has the hardest time of adjusting according to what soul type matches them up in the afterlife.

All people will get an afterlife that best matches how they lived their life during their earthly life. Afterlives adjust after a life is lived and not settled until life on Earth ends.

Please explain your answer and share your top spiritual thoughts!

I am scared something bad will happen to me today if I go to work.
