if not from extant apes... what what kind of species we came from?
Since you had to ask, the current theory is that humans and apes shared a common ancestor which is thought to have existed 5-8 million years ago. One likely candidate is
Australopithecus.
any evolutionst cannot provide fossil evidence where we came from, and yet atheist simply believed evolution?
Gaps in the fossil record exist, but that's expected, and it doesn't disprove the theory in general. But many
transitional fossils have been found.
And no, in general we don't "simply believe" in evolution. The skeptic must weigh it equally with other myths or theories of universal origin, and constantly revisit or re-examine it against newer studies and evidence.
It so happens that current cosmological theory and evolutionary theory are more self-consistent, and are more consistent with other scientific theories on the observable universe and so it makes more sense to believe those, rather than, say, a young earth.
that is "blinded faith"
With all due respect, sir, the term is
blind faith.
And it cannot be "blind" faith if there's theory, science, observation and evidence.
To be fair, it's not "blind faith" either if you seriously study the Bible, theology or catechism. On the other hand, most Christians or Catholics can't claim as much. They just take what their pastor or priest tells them without question. Now
that is blind.
The existence of God cannot be proved or disproved. The Bible says that we must accept by faith the fact that God exists
Two things.
First, of course belief in God requires faith.
Second, and more importantly, if someone believed in the Bible as the Word of God then they obviously believe in God to begin with. So they can't use the Bible as evidence for God because, well, that's called a
tautology.
If you had came from a position where you acknowledge the diversity of various books in the Bible and their origins and literary forms—where some parts of it are allegorical, some are poetry, song, parables, and yes, some coincide well with recorded history—then this would be a much, much more productive and encouraging discussion.
