Where did the universe come from? Atheistic origin science has no answer.

[Wyrd of Gawd]

The universe exists because quantum foam created a particle that continued to evolve until hydrogen was formed.  Once celestial hydrogen in created in a sufficient amount its gravity clumps it up into giant balls.  The balls of hydrogen then go nuclear and a star is formed.  The star's furnace cooks the hydrogen into heavier elements.  At some point the star explodes and throws those heavier elements out into space.  Gravity does its magic and hydrogen clumps together into a new ball which goes nuclear producing a new star.  The heavier elements produce their own gravity fields and clump together into balls of their own.  The whole system eventually equalizes and orbits the star.  Under the right conditions the heavier mineral rich planets will have a solid iron-nickel core surrounded by a molten covering.  The planet's internal furnace will produce heat, gases, water, and other fluids such as oil but only if the planet is "alive" and has sufficient internal stresses.  

Mercury is dead.  Venus is alive but sick.  It's very hot but it does have an atmosphere. 
Earth is healthy.  Mars is on its death bed.  Jupiter, Saturn, and Neptune are alive but their atmospheres are poisonous to our life forms.  

And we are space aliens from the Sagittarius Dwarf Galaxy which has been assimilated by the larger Milky Way Galaxy.  There's no God character in our solar system.
