God could easily have spoken cause a very organized, creative Big Bang!
I, personally, believe a Big Bang could have been the spark that caused this vast thing we call the universe to be. No reason God couldn’t have caused it.

Halton Christian “Chip” Arp (March 21, 1927 – December 28, 2013) was an American astronomer. He was known for his 1966 Atlas of Peculiar Galaxies, which (it was later realized) catalogues many examples of interacting and merging galaxies. Arp was also known as a critic of the Big Bang theory and for advocating a non-standard cosmology incorporating intrinsic redshift.
