Yes I can because the theory of evolution is the only theory for which any observable evidence exists. There is not one single shred of observable evidence that will stand up to any kind of objective scrutiny to support the god theory, so I'll go with what I can show.- Look into the human body, DNA, the unbelievably complex makeup of the human body n how absolutely perfect it is, can you honestly believe that it all started from swamp fungi etc.
There is plenty of evidence around to show that DNA is far from perfect. You just have to start counting up the number of variations of human dis-ease that are demonstrably related in some way to errors of DNA. In a lot of ways it is the imperfections related to DNA that has enabled the whole panorama of life.
I find life in the most general sense is a total "Wow!!!!" experience without any need to recourse to some sort of supernatural 'special friend'.
