What are the odds of an alien civilization forming within 500 years?

Out of that vast range, the odds that an alien civilization would be within 500 years of our stage of development are millions to one — and that assumes that other planets follow the same path as ours, which is a huge leap of faith. But let’s keep digging into the question. How to launch an interstellar probe using a laser lightsail.

Do extrastellar civilizations use technology we cannot see?

True, a signal from an alien civilization might be subtle or sophisticated, but the disappointing silence of the sky may also indicate that long-lasting extrastellar civilizations do not use technologies that would make them visible to our telescopes.
