Who claimed the big bang was more than the best theory we have? I'm pretty sure you didn't watch god create everything.
Regardless of using "circular logic".......you can theorize thousands of creation narratives......but at some point there had to be a beginning to anything that is physical......just as there will be an ending to such when all its energy has been exhausted. How many multi-universes do you wish to speculate upon? According to the Laws that govern this physical reality there must have been a beginning point. Unless you are agreeing to the only other alternative.......the existence of a Supernatural Realm, a realm that caused the physical to come into existence. Which is exactly what the idea about multi-verses preach. Strange bed fellows no? As these universe MUST be eternal to validate such a theory/idea.....but science proves that anything that exists in a physical state can't be eternal when it existence depends upon the consumption and expenditure of energy.
What is this law? Energy cannot be created or destroyed? The Law of Conservation. Which directly falsifies creation by some magic cosmic egg (of pure energy) that created itself from nothing then exploded. Then we have the 1st law of thermodynamics.......which must end with the Universe being a closed system.....which contradicts energy creating itself from another "closed system"........i.e, multiverse? When you chase such ideas......its called circular logic, that always ends back at the starting point......like a dog chasing its tail and never catching it. By Logical Thought...........in order for the Universe to exist as it does today, there must have been a superior (super) creating force to nature (natural).....a Supernatural Cause to the effect known as the Universe. It simply means our universe came into existence via unseen/unknown sources. Thus.......this creating force is SuperNatural.....superior to nature. Just as your other theories must be superior to our natural universe. Again...strange bed fellows no?
Your point? The key word is theory............."any" theory is nothing but human ideas based upon assumptions, conjectures and speculations based upon what is observable today.....i.e, "A WAY OF THINKING", No theory can be proven to be truth void of using the basic laws of physics via applying those ideas to the scientific method. Again......to prove that a theory is a fact of science, the idea must be proven through experimentation to be 1. Observable 2. Reproducible 3. With "Consistency" upon each application, if one of these essential laws of physics can't be proven via experiment.......then said theory is considered to be "falsified" by the scientific method.
Example: Pasteur falsified the idea/theory that life can be generated from non-living matter in the 19th century and his experiments have never been falsified. His scientific conclusions as expressed by the scientific method of Observable, Reproducible Constant results in experimentation proving that Life can only be produced from "pre-existing" life of the same species. Which agrees entirely with the Creation narrative in Genesis. All life is created/procreated........."each" after its "own kind". -- Genesis 1:24-26
But still.......even through Pasteur falsified the theory that life can be generated from dead matter..........this falsified theory is still taught as a fact of science to our children in all government funded institutes of learning.
Challenge: Anyone: present the scientific experiment that has ever falsified CREATION. Just one experiment that proves that life was never created.......... Unlike the theory that life evolved from dead matter...which has been falsified by a thousand or tens of thousands of experiments attempting to create life.......void of using pre-existing life of the same nature. ANYONE? There has not been "1" experiment that has reproduced life from non living tissue.
Who observed creation regardless of what theory/idea is applied as a POSSIBLE explanation? Who has ever observed and reproduced Life being reproduced from dead matter? Who has observed star dust.........created from Hydrogen and Helium via the explosion of a Super Nova evolve into biological life, which is the only possibility for LIFE to have evolved from 2 basic elements (Hydrogen and Helium)......the supposed byproduct of the Big Bang......which generated its own mass/matter from "NOTHING" according to Stephen Hawking.
Who are the one's who believe in FABLES and FAIRY TALES? 1. The Universe (which is proven to be in a state of decay.....non-eternal, via the laws of physics...i.e, the laws of thermodynamics) created itself from nothing. 2. The result of this explosion created 2 elements projected in all directions by the explosion.......eventually these 2 elements formed stars......that in turn created all the elements common to this universe......3. The elements existed in the form of a star until the first star exploded with the resulting STAR DUST eventually cooling off to make solid matter (non living matter) 4. This matter somehow evolved into biological life..........that some how can't be reproduced because of.........? Then, the speculations, conjectures and assumption fill in the blanks void of any type of scientific evidence that life has ever evolved from dead matter. Now......if you believe this narrative, then you must have FAITH because you don't have the science to back up your claims.
