Consider Einstein. At the time his theories were made public, he was some German guy, and it was around WWI, so there was not much interest in hearing from him. There was a lot of hate towards Germans. But, since the theory was interesting, and they did a test which showed his theory could predict physical phenomena, it became accepted and so did he. This is science. It's not science if it is not falsifiable.
