I believe we were created by aliens and combined with animals , that originally lived on this earth.

First off if we were their creations then we would know them, make contact every day, and most likely live alongside them. This theory is really bad though. It doesn't make sense that they did this.

Nobody ever agrees with an idiot.

No.

Your wishes have nothing to do with facts, truth, or reality.

You have quite the imagination. But no I don't agree with you.

My question is
why can't we give a question
a thumbs down ?

I believe aliens could have seeded the first living organisms on the planet, but I don't believe they would have "mixed" us with already existing life. If there was analien race advanced enough to control life in such a way, and probably travel very far, then they would probably know of the destructive effects introducing a new form of life would have an the existing ecosystems.

THere are many other quite destructive species that fight among themselves, other primates being one of them. Before technology and before we became "civilized" we didn't really harm the earth. It's just once we became humans that we started having more negative effects. And even then, it was still possible to live in harmony with the rest of the world as many native civilizations did.

So I believe it could have been possible that aliens planted the first forms of life or maybe the ingredients for life as some sort of massive experiment, but I don't believe they would have altered an already existing world of life.

Darwin wasn't mad, simply observant.

Also, isn't God the biggest alien of them all? He's unknowable, after all. Above our understand, outside of space and time, etc.

There's also the theory that humans were mated with by Angels (Nephilim, the Watchers, etc.) and their children, the Grigori, the Anakim, the Zamzummin, the Rephaim, etc., destroyed most of mankind, mating with them, eating them, until god sent the flood to keep mankind from being totally destroyed. The Book of Enoch, The Book of Jubilees, The Books of Adam and Eve, etc., all speak of them. The Book of Enoch was quoted by Christ on a number of occasions and the Dead Sea Scrolls quotes them quite a bit, too.
