consider what humans will be able to create in 1000 years. They will have the technology to create new cellular forms based on a completely redesigned DNA. And they will have the technology to send that new life form to another solar system in our galaxy. Future humans will be the creators of life on a far away planet. They will be intelligent designers.
Can't it be possible that we were created by a distant civilization of intelligent beings? Unexplained is how was our creator created. But at least a logical case can be made that we could have been created.
