Human alone in the universe with hundreds of billions of galaxies? Really unlikely. That human alone in the world thinking is left over from the medieval thinking...human alone in flat pancake which sun circles.

Sory if I will not answer the question, but allow me to write my own point of view. Only God knows if we are alone in universe, because He is the creator of everything. And I don't agree with you that all things come from nothing.

There could be other forms of life in the universe

Hi... No... we are not alone!
