I can understand how an intelligent individual may have problems with the creation account in Genesis. What I don't understand is how that same intelligent individual has no problem whatsoever believing everything we see in the world somehow came from the so-called primordial soup.
Not only must a particular life form spontaneously arise, but the other organisms upon which it depends must have arisen in lock step. And what are the odds of the flora arising in the required sequence as that of the fauna which depends on that flora? That is more believable than Genesis?
Science is based on observation. Who has ever seen one genus becoming another? Nobody! It's purely inference which is only slightly better than guessing. It is a model that admittedly could be said to fit with some observed phenomena, but there is perhaps a better model that nobody has thought of yet. A model is a model. It is not necessarily a reality.
If one does not believe Genesis it seems it would be better to just say, "I don't know how we all got here."
These are some pretty good questions and I have no answers but you might consider that perhaps life is far more widespread than we believe. It is entirely possible it came into existence on only a single planet but was spread through the cosmos as stars have gone nova. How it came into existence is a perfectly legitimate question but it's entirely unreasonable to suppose that molecular chains grew until consciousness arose in one. Once consciousness exists then it would simply adapt and change to suit conditions. Individuals simply strive to survive.
The change from a chemical to a consciousness may seem an insurmountable hurdle but there are strange chemicals out there and truly stranger conditions. Perhaps it required a Creator to set everything in motion or the Creator engineered all of time and space. But in any case I think there is an answer and I think that it will fit with what is known.
Current beliefs are based on some faulty assumptions and the assumption no God was needed is as irrational as supposing that nothing could exist without God. The job of science is to devise experiments that will lead to knowledge. But until we actually know something we don't really know anything at all. At this point we know virtually nothing at all. But everyone seems to have all the answers anyway and it would never occur to them that it isn't possible to understand "evolution" without understanding consciousness and the origin of life wouldn't exist without consciousness. We can't only not know what we know without consciousness we can't even know at all.
Now believers in science can tell me how they know I'm wrong.
