The good thing about science is that it doesn’t depend on trusting any one person or institution, it depends on a process designed to catch bias and error.
Scientists don’t just publish opinions. Well, they can, but we generally call these people crackpots. However, in modern times they do financially well on YouTube and podcasts. Scientists test ideas through predictions and experiments, share their data and methods, and other scientists try to reproduce the results. If findings can’t be repeated, they’re usually rejected. Over time, only the most reliable results hold up.
Yes, funding and politics can influence science, on all sides. But the scientific system has: peer review, conflict-of-interest disclosures, reproducibility, and open data. These are not perfect, but they make science far more reliable than all other known systems.
What I believe is a continuation of how we built our modern civilization, since the time of Newton, and earlier. I cannot personally audit all of science, so instead I rely on the scientific method, which is the best system (warts and all) that we have yet found to discover the base truth.
