Atheists is it true that you can't prove that something doesn't exist ?
I can prove that a flying elephant doesn't exist on Earth. Because simply if it existed we would have seen it. I can prove that using the laws of probability. The probability of seeing such flying animal would be too high and not seeing it would be an impossibility. I can also prove that a second star doesn't exist in our solar system. I can also prove using science that a star with a mass similar to the mass of Jupiter doesn't exist because it would be incapable of starting fusion. I can prove that there is dinosaur inside my laptop. See it's possible to prove something doesn't exist. So why do you lie and say it's not possible ?
No one claimed that God exists on Earth. So your analogy is failed.
