Look up "atheist" in the dictionary. The group of those who deny the existence of science or that knowledge can be gleaned from experiment is virtually a null set. Why would you even argue about simple facts and definitions.
No. You are describing an "agnostic". The dictionary is not your friend is it?
Great!!! This is progress! Now all you have to do is define "fitness" so we'll know which animal will or won't survive an encounter with a predator and then we can start making predictions about how a species will survive.
Are you aware that a lion will select an individual from a herd before it even attacks? In other words 99.9% of the animals are in little real danger if they can avoid stumbling in the path of the lion. So how does the lion's consciousness affect the odds that it selected the weakest wildebeest.
The theory of evolution is stupid, outdated, and never did describe the results of observation or experiment. Now you'll ignore this post as well because that's what all believers do: They ignore all evidence and respond by reciting doctrine. I've listed hundreds and hundreds of reasons in this thread to doubt Darwin but not one is ever addressed except to gainsay it and then to claim it never happened at all.
Once people start rejecting scientific beliefs in one area it becomes easier and easier to reject others. You say you know "what causes gravity" but if anyone asks what that is it will be nonsensical or not an answer at all. You'll say it's a gravity well like a planet or mass but this is a non answer because even a butterfly knows exactly where the center of the earth is. Birds can even feel the moon.
Change in species exists. We've seen wolves turn into dogs and grass turn into wheat. We can see eyeless animals in caves and even find fossils of what came before. But we can't determine causation if we have no idea if even one lion is going to kill one wildebeest in one encounter. Even though we can't do this you believe that we can just assume that if a proto-lion once ate a proto-wildebeest then one was more fit and the other less fit and this explains everything. You have no theory. What you have is Look and See Science. There can be no science without experiment and no knowledge that doesn't lead to understanding and creation. You have no logic and have merely induced what was believed before. It is nonsense. All the evidence, all the observation, and all the "experiments" say change in species is far more complex than the "Theory of Evolution". You can't understand this because you can't even parse my words Every sentence reads "God did it" when you try to understand what I write so you come back and tell me what doctrine is. Your beliefs are wrong because your premises are wrong.
