Proving something to be accurate by ANY practical means whatsoever is much more difficult and far more useful than just "believing" in it because someone else told you to...and I highly recommend seeking such direct proof for yourself...and listening to MANY viewpoints, not just the officially sanctioned viewpoint of your day. Scientific means are one of several ways to prove that something is accurate, but they aren't the only way. One way you can prove something for yourself, for example, is to DO it or experience it or witness it and use your own powers of observation. You can do that whether or not you are a scientist. People need to learn to trust themselves, not just rely blindly on secondhand information from high and mighty hierarchical authorities such as churches, governments, news services, intelligence agencies, medical authorities, and other professional authority figures. Every society is ruled by such authorities, both religious and secular. Most people trust them blindly...and are often misled by them for a variety of reasons.

In other words, "if you want somebody you can trust, trust yourself" - Bob Dylan
