No, Atheist Scientists Are Incompetent
Recently, a "physicist" by the name of Lawrence Krauss claimed that "all scientists should be militant atheists." On the contrary, any scientist who is not a theist is incompetent.
Let’s define “God” as the “supernatural being who created the Universe.” That is, God is the cosmological singularity. To see this, unpack the definition of “God.” The word “supernatural” literally means "above nature," or outside of space and time, and not subject to the laws of physics. “Super” just means “above,” and the meaning of “nature” is clear if we use the Greek work for nature: “physis.”
The initial cosmological singularity is not in space or time, but rather it is the origin of space and time, the origin of all that is, seen and unseen. The cosmological singularity cannot be in space or time, because it is intrinsically infinite, and anything in space or time, and subject to the laws of physics, must be locally finite. To put it another way, the cosmological singularity is the cause of everything that exists, but is itself uncaused.
The cosmological singularity is the uncaused first cause, which is how Thomas Aquinas ("The Five Ways") and Maimonides ("The Guide for the Perplexed") defined “God.” All competent Christian and Jewish theologians have known for the past 2,000 years that God in His essence is not an old man wearing a white gown. One of the greatest Christian theologians, John Chrysostom, said that no created being can see God as He really is. So He appears to us in a form we can comprehend, often as an old guy wearing a white sheet.
So now that we know that God is the cosmological singularity, the question of God’s existence is now a question of physics: Does the cosmological singularity exist?
If we accept the laws of physics, the answer is yes.
