I'd never met aliens before and I only saw them in movies, but I do believe on aliens existence in the entire universe. 

I believe in God because I am a Catholic.  I grew up from all the teachings from school and church about God. God is always there in good or bad times. 

I'm not in favor of death penalty.  We are not allowed to kill anyone.  But that's from a point of view of myself when I was younger. But now I am in favor of death penalty coz those criminals are not human.  If you see them killed a whole family.  That's alarming.  Punished them with death penalty so that the future criminals will be hesitant to do such crimes.
