My answer to If an alien species came to earth, what it would look at earth creatures, and would it be able to dist…
Answer by Desmond Last:
They will look exactly the same as we do. Obviously they would not be as destructive as we are and want to destroy our Planet and kill each other.
But why would they look any different?
We inhabit a biological system that has all the necessary chemicals and the right structure of those chemicals to maintain life.
It is not possible to reproduce life in any other form with anything less or more than that which we have.
Now for the real proof. For those of us who believe in the Faith of God why would he go to all the bother of creating a being that is any less than the ‘perfect’ we are.
We have (except when we are not killing each other) intelligence, emotions, imagination etc.
We may be the ancestors of all beings in the Universe. We could be God’s first experiment to put a form to his own belief.
That would mean that some of us would have to survive the End of mankind that is coming unless we change our ways.
If there is an end to mankind possibly some of us survive to become the ancestors of those who come from other Galaxies to Planet Earth.
They could be here already and as they look just like us.
Perhaps they have come to see who is going to survive the end of mankind to become their ancestors.
