I would suggest then that you have a fundamental misunderstanding of how science reaches its conclusions. Unlike religious beliefs it isn't about simply believing in written words typically anonymous and one person witnessing to others. Science is primarily about evidence and the explaining of it, not a belief or faith in a person. Scientific conclusions are presented so that anyone else, in theory, can review them and show them to be false, if indeed they are, based on the same or better evidence. Evidence-free bald assertions are not falsifiable while scientific claims are and can be demonstrated to be wrong if evidentially so. If I read a scientific publication I don't simply believe in the author, I expect there to be plenty of evidence presented to back it up and that it has been subject to peer review.
I think that you have a twisted concept about what science is. Plus that you are confused between how science is verified and how a scientific truth is conveyed.
Science is discovered and verified mostly through its predictability. This requires a lab setup to achieve. The conveying of a scientific truth however is through faith. As it is a very inefficient route if every single individual will have to rely on a lab to verify the truth by himself. The most efficient way for a human to approach such a truth is that they have to have faith in what have been written down by a small group of humans (the scientists). Peer review reports are just yet a form of human witnessing.
In a nutshell, humans rely heavily on what have been written down by a small group of humans thought to be the direct contact of a truth. It is a process of human witnessing.

To me, humans usually apply fallacious concepts without their own awareness.
Science usually goes through 3 stages to determine a scientific truth,
1) Observation
Science is basically dealing with a set of rules behind a repeating pattern. Observation is achievable basically because the pattern itself can be repeated infinitively. Say, you can observe how the earth revolving around the sun because the number of times the earth revolving the sun is infinitive.*
2) Formulation
Through the possibly infinitive observations, you can develop theories about how it repeats. You can then try to quantitatively describe how it repeats, say, using a formula.
3) Prediction
Prediction is to put your quantitative descriptions (formulated rules) into tests. If they predict correctly, the set of rules discovered/formulated by you is considered a truth (a formal scientific truth). If the prediction fails or doesn’t fail within an acceptable variance (say, due to equipment capability limit), the set of rules you developed is considered falsified.
To simply put a set of rules behind a repeating pattern is considered "proven" when the prediction of the pattern using this set of rules doesn't fail.
For an example, water dissolves into hydrogen and oxygen. This holds true no matter what. That is, you make a prediction (that water must dissolve into H2 and O2) before each and every experiment and that your prediction will never fail. You deserve a Nobel Prize shall your this prediction actually fails.
A human brain thus realizes/recognizes that it is a truth as the numerous predictions never fail.
This is the nature (predictability and falsifiability) of what science is.
