It is easy to demonstrate that the anthropomorphic god of religion is a fallacy. However, when it comes to discussing the hypothesis that a living entity created our universe, it becomes more complicated and relevant. In order to do that, you would have to demonstrate at least two key ideas. Firstly, you would have to show that the Universe is structured intelligently. This has already been done by discoveries made through science. The second one to prove is that there was an intention behind the creation of our universe: this is tougher to demonstrate but it may not be impossible.
The anthropic principle
Simply stated, “The anthropic principle is a philosophical consideration that observations of the Universe must be compatible with the conscious and sapient life that observes it. Some proponents of the anthropic principle reason that it explains why this universe has the age and the fundamental physical constants necessary to accommodate conscious life. […] The strong anthropic principle (SAP) as explained by John D. Barrow and Frank Tipler states that this is all the case because the Universe is in some sense compelled to eventually have conscious and sapient life emerge within it.”Science has effectively shown that there are many natural physical constants that are so rightly tuned that the universe, stars, planets, solar systems, galaxies and even life can exist. Very small decreases or increases in those constants would have made all of the above impossible. Therefore one may wonder if it happened just as a streak of coincidences. Considering this as true would be like buying lottery tickets in many countries and winning the one million jackpot each and every time: this is statistically very improbable. Hence one may see this as a strong argument for intention but it cannot completely eliminate the factor of randomness: that’s when comes into play the concept of determinism. It is also important to note here that one may argue because of the multiverse theory that our universe is only one among millions where life does not prevail. The problem with that theory is that parallel universes have not been discovered or observed (as far as the public is told): it is purely a matter of faith.
The theory of relativity, Laplace’s demon and the free will-determinism paradox
According to determinism and the law of cause and effect, Laplace’s demon asserts that “if someone (the Demon) knows the precise location and momentum of every atom in the universe, their past and future values for any given time are entailed;” The theory of relativity also posits determinism because two events may not happen in the same timing sequence depending on your position in space although there are assured to occur. In other words, past and future are already part of the present because they are determined. For instance, suppose you fly around a black hole with a spaceship. Time is known to be influenced by speed and gravity. Since a black hole presents very strong gravity, time is much slower than at the surface of the Earth, therefore you would see the future of the universe unveil before your eyes until its end (the big crunch) in a very short time. This doesn’t mean that free will doesn’t exist even though it is paradoxical. Imagine you watch a football match you recorded on TV, all of it is already determined; you know in advance the final score. However, when the match happened, players had the free will to make a pass left or right. Just like Lao Tzu stated 2500 years ago in the Tao Te Ching that paradoxes were inherent in Nature through contemplation, recently science proved they existed. For example, take the wave-particule paradox which is interpreted as a duality: As Albert Einstein himself puts it, “it seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind of difficulty. We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do.” All what this means is that everything in the Universe (including the appearance of life) may have been determined from the beginning: the big bang. This doesn’t exclude the premise that we possess free will because those two may not constitute a true duality, and subsequently, an opposition.
In conclusion, there could have been an intention to create an intelligent universe where life would exist, therefore providing an argument in favor of “God” as a creator.
