How can Atheists trust science if a non-material realm of ideas and truth does not ex

[Edward the Theist]

If the universe consists of a material realm only and there is no such thing as a non-material/spiritual realm of higher ideas and absolute truth. If our reason and science is only the interactions of matter upon matter and has no basis in a non-material realm of absolute truth then why should atheists believe in objective truth? And if atheists do not believe in objective truth than how can they trust reason and science? How can one trust reason and science as a path to objective truth if objective truth does not exist?

I think for them it's just a matter of whatever works is true. There is no objective truth, per se. By all means, atheists, correct me if I'm wrong.

As for me, I don't worry so much about truth. I see things as being the way they are because to be any other way would result in an impossible contradiction. In other words, I believe that when I finally uncover the ultimate truth of the universe, I will find it simply is the way it is because it can't be any other way. Thus truth for me is a matter of discovering the necessity of the universe.
