Is there any truth to the claim that science has gives us answers based on evidence, whereas religion does not?
I'd say so.
But I'd make the distinction between useful answers and useless ones. Useful answers are those that explain how observable phenomena occur, and can be used to predict future outcomes. If your answer can't do that, or even be demonstrated to correlate with reality in any way, then it doesn't matter if we call it true or false. It's what logical positivists would say isn't even wrong, because it cannot be shown to be right or wrong. They are meaningless ideas since they can't be used for anything.
Faith-based systems of thought are not empirically grounded, and thus have little practical value. They are not derived from physical reality and therefore cannot comment on it in any meaningful or useful way.
Compare the answer to the question of where the tree of life came from. Christianity, for example, says that its God created them (creationism). Science gives us the theory of evolution. The first answer wasn't derived from the study of nature, and can therefore make no predictions about it, either, nor explain how it was done. That's not a useful answer even if correct. Because the scientific answer is drawn from the consideration of physical evidence, it can unify it all in an overarching narrative that includes a mechanism (natural selection applied to spontaneous genetic variation), and accurately predicts what cannot be found in nature and what can. It also can be used in fields like agriculture and medicine to make life better.
So, yeah, creationism gives us answers, but because they are not grounded in evidence, they are not useful even if correct.
How do you know that the scientists perception about the things they infer, are reliable?
Empirically - by observation, by an idea's predictive power. What more do you need to know about the validity of the science and engineering underlying the Apollo moon missions apart from the fact that the crew got to the moon and back to know that the assumptions underlying the mission were valid?
scientists are required to begin, continue, and end their research on the premise that a First cause, an Intelligent Mind, doesn’t exist.
That’s the flaw.
That wouldn't be science. It's the same mistake that the intelligent design people made in reverse when they assumed that there is a god, which generated pseudoscience.
Proper critical thinking evaluates evidence without preconception and goes where reason takes it. If that leads to a God, science will find it and be the first to let us know that it did.
Here you make a claim "it's obviously made up nonsense" without evidence. Applying your "rule" in the above first quote of yours. We can dismiss your claim. Right?
Yes, if by dismiss you mean fail to believe it. That is not the same as declaring that the idea is incorrect. If he can support his position and is willing to do so, we should consider the argument critically. If we find the argument and the evidence supporting it compelling, we are justified in accepting the ideas as correct (provisionally). And if he doesn't feel like doing that or can't, you are free to not accept the idea as correct. Unsupported claims can be filed under "somebody's opinion, maybe correct, maybe not."
Does science accept or even consider a Mind as a Cause for biological complexity? Or for physics?
Science doesn't exclude the possibility, but presently, there is insufficient evidence to support that belief. As others have noted, inserting a god into any scientific theory or law adds nothing to its explanatory or predictive power, so why do it, especially since there may be no such thing as a god.
Compare: E=mc2, and God ordained that E should equal MC2 and made it so. OK. Can't use that extra bit to do science, making it irrelevant at this point even if true.
post some evidence [that "the evidence for common descent via evolution is overwhelming.]
If your interest is sincere, it's your job to find it.
There are several ways that you can get up to speed on the science. I learned it from textbooks and professors taking university level courses in evolution, and then later, reading popular science books and scientific web sites like
Talk Origins. Or, you can begin with a Google search and just begin reading, but be certain to visit only sites interested in teaching science rather than promoting any other agenda.
How about you explore the Talk Origins link and return here to tell what you learned - what they claimed was evidence of common descent, and offer opinions about what you find believable, and what you don't and why. That's how this material is learned.
And it's excellent training in critical thinking, an acquired skill. See the evidence available to Darwin and the argument he offered to conclude common descent. If you do it in a university, the professor won't even ask you if you believe it, just whether you understand Darwin (and the evolutionists that have come since and added to the theory, such as Gould and punctuated equilibrium - what evidence led to that conclusion).
we have a well tested theory of how biological complexity came about and no mind is indicated or needed, quite the opposite, in fact. Any mind that did things this way would be deranged and/or making an attempt to deliberately deceive.
Ask yourself what would be the result if evolutionary theory were falsified, perhaps by the discovery of a partially digested human being in a dinosaur's belly, or a dog giving birth to a cat naturally. Let's say that the consensus of scientists is that the theory has bee disproven. What now? Christian creationism? No, it's already too late for that even if the science is wrong. The mountains of evidence supporting the theory until the day it was falsified don't disappear. It just needs to be reinterpreted in the light of the falsifying find.
And that's where deliberate deception comes in. What's left but some form of creationism (not necessarily by a god) that was meant to appear like a natural, unguided process? The geographic column of successively older (radiocarbon dating), deeper, and less modern appearing forms would have to be a deception planted there to fool us. That pretty much rules out the God of the Christian Bible, who we are told wants us to know, believe, love, trust, obey, and worship Him. That god didn't do this.
