They have also gotten jobs based on the same, if they were truly as ignorant as you seem to be saying ("Therefore did they really learn anything?") You can say all you want that what we do is to look for answers that reinforce what we believe, but you do the same.
The difference, to me, is that I go in with an open mind. I don't really know much about quantum physics, molecular pathology, or genetics. However, when I read about them, I learn new things, and then I hyopthesis further, read more, learn more things.
What I know about these topics changes as I learn more; gain more knowlege. I don't have to try to fit what I am learning to a pre-determined end point. True believers will be limited in their learning because what they learn must conform to what they've been told (religiously). Otherwise, they wouldn't be a true believer.
You can claim to be unbiased in your view toward research, the world, or the universe, but I think everyone has a bias, therefore from your perspective things seem to disprove God, and from mine the same research and findings prove to me the opposite.
I would never claim to be unbiased, as you said, everyone is. But a bias is different than religion. I may have a bias towards a certain product, but if research proves that that product is inferior, I would abandon my bias. Since religion can never be disproven, a true believer will not do the same. Thus their learning/knowledge is constrained.
As far as "learning anything" goes, that's pretty arrogant of you to say that because we don't come to the same conclusion we never really learn anything, I know just as well as you do that the world is round, and that the universe is expanding and that there are planets out there that are/were capable of holding life, I was intrigued when Pluto was demoted.
Actually, the learning anything question was to ask you how you determine what learning is. To me, having a set-in-stone end point seriously limits learning. That's my opinion, it may be arrogant, but that's it.
As far as the world being round, why do you think so? Because science has determined so? If science says one thing, and religion another, a true believer will always choose to accept what their religion says.
Anyways, I could go on and on (Some probably think that I already have too much), but if you apologize for calling me ignorant then we can call it pax....

(I know you didn't actually use that term)
Yeah, I didn't use that term, I would be very careful not to. I can't offer an apology on this one because it seems that you're taking offense to my opinon, and since my opinion hasn't changed, it would be a hollow apology. And I'm not in the habit of making those.
I can, however, say that any opinions I have expressed here have been in a knowingly impossible attempt to get "the other side" to see/understand my side. Any negative feelings derived from reading such opinions are a by-product of the message, not the intent.
