Do you believe in extraterrestrial life which is also called alien life? It's hard for me to believe aliens life lives outside of earth and didn't originate on earth.
What exactly does that mean though?
Do you believe in aliens? They hypothetical beings range from simple prokaryotes to advanced civilizations that are way more advanced than we are as human beings on earth.
Ok, then ... I guess I do! Why can't there be other life like ours?
It's just hard for me to imagine I guess. We have been searching since the mid 20th century for any signs of extraterrestrial life.
And have we found any? 
Not that I am aware of! lol There have been searches with telescope and specimen data to radios used to detect sounds and signals from outerspace.
Oh well, maybe we are an experiment... and other life forms are above us watching.
You never know! lol The concept of aliens and their intelligence has had a major cultural impact in works of science fiction. So, the quest and search continues! lol
