Why is evolution hiding?

[MJ the Skeptical]

I'm wondering if some "atheists" reject the belief that life arose from non-life and evolved from simpler creatures to more complex life forms; tiny cell becomes an amoeba, then a lizard, then a monkey, and eventually you !

You can believe either way as a theist or atheist on how biological life arose. So I don't see why you're only addressing atheists unless we just go with the assumption that most of us on this forum are atheists.

I know that evolution is indeed a fact but the belief that different types of animals evolved into other species is not fact or we would see them "evolving" into other types or at least need to see this to say it is fact.

Yes is it a fact and if you have no problem with Evolution you shouldn't have a problem with "macro-evolution" either which is just lots of "micro-evolution events" over time.

Where is the evidence of cats, dogs and horses gradually turning into something else? We do see changes within species. We also see no evidence of gradual change in the fossil record either.

Funny you mention dogs and cats because they come from some of the best known lineages in the fossil record.

And again, false, we see changes in the fossil record and distinctions of how old they are.

Isn't Evolution still called a theory, a possible explanation or assumption, because it is not testable according to the scientific method?

No. A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirmed through observation and experimentation.

The definition of Scientific theory pertains the Scientific method...

I lean more toward agnosticism actually. I have no proof there is a God.

That's a typical Elitist Agnostic dodge.
