what does the bible say?
Nature clearly demonstrates evidence of creation (Psalm 19:1; Psalm 139:14; Romans 1:20). Creation is the act of bringing something into existence based on a design or idea. So Genesis 1:1 means God not only created the universe, but also designed it. Further, Christ now sustains the universe (Colossians 1:17).
The physical parameters of the universe and the information-bearing properties of life support modern Intelligent Design (ID) theory. This evidence points to a transcendent designing intelligence (God).
Astronomical evidence proves that the universe had a beginning, which the Bible has said all along (Genesis 1:1). Observational evidence includes the expansion of the universe according to Hubble's law (as indicated by the redshifts of galaxies), discovery and measurement of the cosmic microwave background, and the different appearance of distant (early) galaxies. From the Kalam cosmological argument, we know if the universe had a beginning, so it had a first cause.
