Why in an electric circuit with only a generator the resistance R=infinity?

Because you don't have a completed circuit. Just an open. Of course, in reality the resistance isn't infinite, just very, very high. But we call it infinite to simplify things when teaching things to students.

Also, there's no need to throw half a dozen question marks into a sentence. One will suffice.

Because the current is zero.

What's "a generator" in your question? Can you post a schematic?

As worded, the question implies to me zero resistance, not infinite. So yeah, we need a diagram.
