first off, the big bang: how can you say everything you see came from a small speck of dust smaller than this period. ? i know a couple of you would say you need lots and lots of energy, but where would you get this energy from? according to the law of conservation of energy, "energy can not be creating nor destryoed." in a chemical reaction, energy is never created nor destroyed, rather, it's used up to create the new substance, then released as one form or another; we humans can detect energy as heat, but there can be other forms. back on subject, this speck was in a realm of nothingness, so where did the energy come from?
next, it has been proven time and time again that LIFE CAN NOT COME FROM NONLIVING MATTER. this theory is called biogenesis, and is false. Louis Pateur proved this. and, according to evolution, lighting struck the ocean's waters, and amino acids, the basis of DNA, was created. DNA is too complex to have been created by chance. think about it: in DNA, each and every segment of it controls what you look like, how youll function, if youll be deformed, if you'll even live orn not beyond birth, etc. if just ONE crucial part of this DNA is screwed up, the whole thing's screwed up, and the organism can't live. if this happened by chance, as said in evolution, the odds would be way too high for none of the crucial parts to not be screwed up. still with me? good
third, even the simplest of bacteria are too complex to be made by chance! have you seen the inside of a bacteria lately? take a look:

this is the most primitive they get, and can you tell me that was created by chance? sure, it looks simple, but the odds of some lightning striking, creating amino acids, making organic matter, it all coming together to form that is very unlikely!
evolution states that the changes came from mutations, from adaptation or maybe from birth defects. the only problem: gene mutations are recessive genes! which means it requires two recessive genes to make a dominant gene. lets use a pre- giraffe, with a small neck, about the size of a horse, for this example. let's say it had an offspring with a bigger neck from a mutation, since wild animals can not get obese for their kind, or be large, like humans or domesticated animals. this offspring would have to mate with another one with that same mutation for it to become a dominant trait. this would be very unlikely in the wild.
of course, the offspring of the offspring with the mutation could pass his genes and his offspring become carriers, which means they have the gene but dont show any signs of it. this couldve been how stuff was passed on by evolution. and as more and more mutations of this kind came around, the necks got a little longer each generation. but, there's a problem! their necks would be too long so they cant eat smaller plants, but too small to eat the plants higher up.
lastly, can you really look at all the complex life on this earth and say that chance made it all? it's a hard thing to say yes too, because of the more complex things such as a bat's sonar, a bug's multilensed eyes, a dolphin's sonar system, a bird's hollow bone system, to help them weigh less, a fish's gill system, our different bodily systems(respiratory, circulatory, etc.), and much more. can you really say "bacteria HAPPENED to become multicellular bacteria which HAPPENED to become primitive ocean life which HAPPENED to become complex fish which HAPPENED to sprout legs and grow lungs which HAPPENED to become reptiles which HAPPENED to become complex reptiles known as dinosaurs and small mammals which the dinosaurs died out and the mammals(read: rat- like creatures) HAPPENED to become complex mammals which HAPPENED to become all this complex life you see today? hard to fathom for me
i know all you can probably tear this arguement up, and id like it if you tried, i made this because 1) evolution is a theory which sounds almost ridiculous, but reasonable enough for scientists to accept it, and 2) because there's enough religion bashing threads on this forum. thanks for your time!
