What if Gods are related to aliens?

According to early Egyptian mythology, people in ancient Egypt used to worship gods which represented creature with half animal body and half human body. Evidences of these are found in the paintings preserved in the great pyramids of Egypt. Historians believed that these may be aliens, who came in this earth thousands of years ago to give values and teachings to the humans of those times and they don't come now because, humans have now become full of greed, jealousy, anger and to the most extent share heated debates amongst themselves. All these sins of humans don't make those 'godly aliens' ever return to earth again.

But this fact has no logic.

If gods were aliens, then they came from some other planet or solar system. So, to make this journey possible, some kind of spaceship or a mode of transport had to be used.

So, if this is true, then just like those, the paintings of gods coming from space via a spaceship had to be painted, at least to some extent in detail. But no such painting as such has been found yet.

And after all these are just paintings! Paintings can be drawn with one's imagination too.

Hence, this is sure that there are 'no aliens, whom we can term as GOD'.
