You can find scientific papers on Google if you know how to use it.

You can find scientific papers on a lot of search engines, not only Google.

The problem with that is, that you still need to know how to interpret any results and statements within the supposedly scientific papers. If you are not a statistician, you might overlook methodology mistakes. If you are not an expert in the matter of the paper, you might not realize some side condition, that makes some statement or result of the paper irrelevant for your individual situation.

I do, but surprisingly a lot of people do not.
