Creation v.s. Evolution

I've heard of dark matter and how it's one of the most mysterious aspects of space. It's not something we can prove physically, but with certain calculations and mathematics if I'm correct. I can't disagree with the whole "space is expanding". Space is afterall like a fabric, constantly stretching and expanding, so in essence, the Big Bang may have correlation with that. I don't want to pretend I know much about space although it fascinates and scares me all at the same time. So are you saying space or more correctly matter always existed? An analogy I've always used with the Big Bang, and why I'm skeptic is: All that matter is like gasoline with a lot potential energy. The Big Bang is like a spark dropped into that gasoline and ignited the beginning of what we know/see. Are scientists still trying to figure out where that "spark" came from or is there a theory for that one too? I looked into the study of DNA slightly, but I am by no means that knowledgeable in it. As far as I know, every species, with their sub families have a DNA code that dictates what one looks like, sounds, etc. More often than not, that DNA code cannot be changed. I'm not really sure where this thought was going, but I'll leave it in here in case one of us solves that problem haha. To be defined "alive" there have to be a list of criteria met (I believe there are 7): 1) Have DNA (I'm positive this is one of them but correct me if I'm wrong) 2) Reproduce 3) Respond to changes in its surroundings 4) Have metabolism and breathe 5) Made of cells 6) Maintain homeostasis 7) Pass traits into offspring I was going to add growth/change but I feel that may fall under DNA somehow. We can all say, without a doubt, that rocks aren't alive. Life couldn't have possibly existed during the explosion of the universe, so where did it come from? As a Theist, I would say G-d created life in 2 days. He gave them the "Breath of LIfe". As a result, I would say life came from G-d, and is therefore not necessarily only a "physical" thing. What would be an Atheist's take on life? My above life criteria was created in response to your sperm statement. By following those criteria I would not say sperm are alive. 1) DNA - Sperm do contain a large portion, if not all, the DNA required to create life within a womb. But I don't think that DNA is used by the sperm but more like stored by the sperm for the egg. DNA are helix strands, and if I'm correct, sperm is basically intertwined DNA helix'. 2) Reproduce - Sperm do not reproduce, they fuse with the egg. 3) Respond to changes in its surroundings - Sperm don't follow a specific pattern or path when released into the uterus. They will move/wriggle until they happen to find the egg, in which case the process starts. So I don't think we can say it necessarily responds to its surroundings. The average lifespan of a sperm is 3 days, but max can be 5 or lowest can be a mere few hours, depending on the condition of the uterus (fertile cervical fluid). 4) Metabolism and breathe - Sperm do not have a metabolism to process energy and no way to obtain said energy, hence why their lifespan is incredibly short. 5) Made of cells - I'm not 100% sure on this one. 6) Maintain homeostasis - Sperm cannot do this because they have to be in the perfect temperature range or they will die. 7) Pass traits to offspring - Indirectly it does, yes. Sperm can't make offspring, but they do contribute to the creation of a fetus. Why do you see sperm as being alive?
