I agree, and perhaps you should tell certain scientists to stop with the formulations of these pre-big bang models which are meant to restore an eternal existing universe.
But that takes all the fun out of it. Science is driven forward by blindly reaching into the universe and hoping you grab a good theory. Its driven by human creativity in an attempt to explain the unexplained. To that end, scientists find it *fun* to think about crazy possibilities. A scientist may publish a hairbrained idea not because they believe it, but because it might spur others to think of something more in line with reality.
In other words, sometimes science is dropping a mentos (Your crazy idea) into a bottle of coke (The scientific community) to see what pops out (Genius!).
Also remember that *nothing* in science is beyond questioning. The strength of a theory is based on its predictive power, so if another theory has better predictive power then it will supplant the prior one. To this end, yeah the BGV puts limitations on universe origins, but that doesn't mean its all holy, it can be replaced by better theories with more predictive power.
I want to you to take all of the physical matter needed to configure a human brain.
And I will give you the benefit of the doubt and say you may be able to shape and mold the perfect human brain.
Next step...
Give this brain consciousness.
Go ahead, have at it.
If you can accomplish this, not only will I be shocked, but I will be impressed.
This strikes me as a god of the gaps argument in the form, "We don't know how consciousness arises in the brain, therefore God is the cause of consciousness." But this is a very dangerous place to put your faith--there have been many gaps in our knowledge where people found God, only to have a naturalistic explanation arise that answers that gap effectively.
We don't know what comprises consciousness within the brain, but we do have pretty good evidence its a product of the brain. Brain trauma has been linked to changes in personality, memory, and awareness. Phineas Gage, acquired sociopathy, changes in impulse control, changes in interest ways of talking, basic preferences are all examples. I have a whole book on Phinead Gage called "An Odd Kind of Fame."
During the height of the lobotomy craze in the US, behavioral and personality changes were documented as a product of these procedures. People were getting minor lobotomies (They weren't called that at the time) specifically to achieve these personality, impulse, and behavior changes.
Another line of evidence is de-cerebrated animals. Removing the neocortex in mammal structures have shown an elimination of what we consider cognitive indicators.
And not evidence, but association that might prove valuable later, we find that across species branches (Avians and mamals specifically) cognitive indicators are associated with isolative structures (neocortical columns in mammals) with long axonal interconnectedness between these structures.
So there is a lot of strong evidence that the brain has a lot to do with consciousness.
