Good evidence and not so good evidence

What is the purpose of science? Why do many people outside of religion believe in the scientific process?

It all comes down to this: evidence.

Most religion can be given to us through anecdotal evidence. Someone has an 'experience' a story they share. This story attempts to explain something. We believe that something usually on the basis of the person's character telling the story.

But really, that story, or anecdotal evidence, is a very small amount of evidence. That's why most reasonable people do not believe in stories. It's not that they are inherently false, it's just that the amount of evidence is not very large. Without a lot of evidence, reasonable people do not believe it.

That's where the scientific method comes in. This method is more believable because it creates massive amounts of evidence, which is more believable to reasonable people than a story. Not only that, but anyone can preform the same test to see if they get the same evidence. If many people across many different spectrums receive the same evidence, then that is something one can reasonably believe in.

Science can be wrong. Science is simply the means of gathering evidence in an attempt to explain something that happens in life. They believe there to be a cause, they test this belief multiple times, and that evidence results in a conclusion about how that thing happened.

Things change, more evidence arises, sometimes in contrast to the previous evidence, and so people will alter their belief based on the evidence.

This is reasonable.

What is not reasonable is a belief in a story with no evidence whatsoever. It is not reasonable to believe in something without any evidence for that thing's existence. If you claim something, but you have no evidence to support your claim, it would be unreasonable to believe in your claim.

People that believe in religion make many interesting claims. However, they only support their claims with stories. This is why reasonable people will not believe your claims, because there is no evidence to support them. And reasonable people only believe something if there is evidence for its existence.

Science is just a better way at getting more evidence to support claims.
