Religious belief involves lots of absurdities. For me, one of the biggest ones is the assumption that humans are the Big Deal of the universe.
Whether it be Christianity, Islam, Judaism, Hinduism, or some other major religion, theologies differ about how people are special in the eye of God, Brahman, or whatever, but they agree that members of a recently evolved species on Earth, Homo sapiens, occupy a central place in the cosmic scheme of things.
This is really difficult for me to accept for various reasons. One is our modern understanding of the size of the universe. Consider...
(1) Light travels 5.88 trillion miles in a year. That's 5,880,000,000,000 miles. Impossible to imagine, right? I mean, the Earth is about 25,000 miles in circumference. That's a long way to go. Traveling almost 6 trillion miles in a year: mind-blowing.
(2) The Milky Way galaxy, where we are, is about 100,000 light years across. So to get from one end to the other, you'd need to travel 6 trillion miles every year for 100,000 years. Even more mind-blowing.
(3) There are lots more galaxies in the universe. Best estimate is 100 billion to 200 billion. This means that in the entire universe, there's around 70 billion trillion stars. Our Sun is one of those. One. Of 70 billion trillion.
(4) Even though the universe is 13.8 billion years old, the size of the observable universe is much larger than 13.8 billion light years, since space expands faster than the speed of light. So the distance from Earth to the edge of the observable universe is about 46 billion light years.
(5) As noted before, light travels about 6 trillion miles a year. So the number of miles to the edge of the observable universe is 6 trillion times 46 billion. Too far to walk, for sure. Even at the speed of light.
I can't begin to visualize how large the universe is. The human mind isn't used to such scales.
Religions, though, come from a pre-scientific era when the size of the universe was considered to be little more than the Earth, sun, and a few nearby astronomical objects.
(HInduism is sort of an exception, in that it posits a cosmos that is vastly old and vastly large, coming much closer to the scale of what modern science tells us is true, while being wrong about many other scientific things.)
So how can all this -- the incredible vastness of the physical universe -- be all about us? I've never seen a cogent explanation from a religious perspective.
Even if one assumes that God or some other conscious creative power exists, and it cares about humans in some special way, why go to the trouble of fashioning such an immense universe if the purpose of creation has something to do with us, Homo sapiens?
