I'm not sure what you mean by this, and in so far as I can understand it doesn't seem to be true. Physicists use the real numbers all the time which are an infinite set.
The problem there is that certain specific models of physics end up giving infinite values for measurable quantities - this is a known problem and has been an area of active research since early work with renormalization in the 1930s. This is not at all an attempt to banish infinity in any general sense.
Now, when there in no God, the Infinity is its substitute, most people would love to exist. But it's just another blunder.
This is rhetoric without content.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
