First, contrary to popular belief, the Big bang theory does NOT say that something came from nothing. In fact, the basic Big bang theory says nothing at all previous to the time of nucleosynthesis (although extensions of it do).<quoted text>
And yet science expects the world to accept its theories about a big bang and evolution at face value despite the lack of evidence that something comes from nothing and one species can magically turn into an entirely new species.
Second, speciation is not a magical process. it has been observed in the lab and the evidence for it extends to the very DNA in our bodies. You lack of understanding of a concept doesn't make the concept wrong.
No, the one making a positive existence claim is the one with the burden of proof. in this case, you have the burden to prove the existence of an intelligent designer. Now, there are certainly ways that you could go about attempting to do that: archaeology has a lot of material on how to distinguish designed artifacts from natural ones. But, nobody on the ID side has been able to give even one shred of evidence of a designer for life, the universe, or anything outside of human design.I've never doubted Intelligent Design exists, but you do and when you claim it does not them the onus lies with you to prove it.
