Do aliens exist?

I am a strong believer that we can not be the only intelligent life in such a vast space in this universe. There are millions of galaxies and even tho i strongly believe in a creator i cant except our Creator stopped with us. I always wonder how our creator GOD was created, and let alone is or are there more in GODS liking.i know our creator has humor , love , and all the same feelings as us, or we would not have these such feelings. I just wish human kind coukd get past greed, selfishness and jelousy so we can move foward.
