I have posted on another topic thus: That the limit of our brain(understanding to a correct conclusion).Could be god for some, big bang, black hole, anti matter for others.
The physical makeup of our brain determines how clever we can be. No matter which person calls upon it for understanding. I personally concede that there may be things we are actually unable to understand because of the physical make up of our brains.
However scientific conclusions are based on proof, if that proof is seen to be unsound, science has no issue with further research to reach a correct result.
Whereas theists / deists will believe without proof or question.
