Do atheists kneel down every evening and pray - to science?
Not to my knowledge.
Do atheists go to the holy Church of nothing every Sunday and pray - to nothing?
Yes. There are a number of atheist churches -- enough, at least, that one made the news some time ago for breaking-off from their parent church over some silly difference.
Do atheists have radio stations that other atheists preach to them from some book and ask for money? For nothing?
Yes, including television shows. This isn't counting the countless online radio, video streaming, podcasts, video series, and other similar media programs. Yes, some even ask for money.
Do athiests go on missions from their atheist church to convert people - to nothing?
Yes. Yes they do. Not just specific atheists churches, mind you, but outreach is a big part of a number of atheist communities.
That's just for fun. The trouble you're having is in defining religion through superficial trappings. It's like saying something isn't science because there aren't sufficient beakers and lab coats around.
