In the previous post I mentioned that science does not provide proof of the existence of God, but it does give inklings. In a book I wrote, which was published in Spanish in 2013 with the title ¿Es compatible Dios con la ciencia? Evolución y Cosmología (Is God Compatible with Science? Evolution and Cosmology) I described a list of those inklings. Here I will summarize a few of them. The first three are scientific, the others are not.
1. The universe is a physical object. During the 19th century, atheist philosophers denied that the universe is a concept applicable to a concrete object that exists outside our mind. The universe is usually defined as the set of everything that exists. According to those philosophers, such a set does not exist, since the concept of the universe is an invention of the human mind, which does not correspond to any physical object. Therefore, it would not be necessary to look for its origin (its cause) outside our mind. This argument was disproved in the 20th century: Einstein’s theory of general relativity leads to a cosmological equation that applies to the universe, which implies that the cosmos has real existence, that it is a physical object.
