Well, aliens creating mankind would be a much more scientific explanation if proven.
Aliens could for example have mixed their DNA with the DNA of Earth primates (monkeys) and then mankind was born.
That explains why we share a lot of DNA in common with monkeys, but we have a more powerful brain (to the point of making up Gods).
Jesus also said "In my Father's house are many rooms". Maybe he knew aliens created us and the space has many civilizations. Maybe his father governs the universe.
I wouldn't worship them. But I'd be friendly to them and try to learn as much as I could.
