I can point you to millions of documented cases of people building houses. Can you point me to a single documented instance of gods creating universes? Do you not understand why your analogy is flawed?
No as I said the existence of a house makes the claim the house was intentionally built more probable than if houses didn't exist. If no houses existed the claim houses we're intentionally caused would be falsified. The same would be true if only one house existed and we have no idea how it got there.
A better analogy is like detectives who come across a corpse. They put up tape all around the entire crime scene. One of the detectives believes its foul play the other believes it natural causes. Without any other information they both have at least one fact that supports either claim. A corpse supports the claim the death occurred to natural causes but it also supports the claim it was intentionally caused. Because either claim requires a dead body. The claim the universe was caused intentionally is supported by the existence of a universe. However the claim without God or a Creator doesn't exist doesn't require a universe to exist, or stars, or planets, or gravity or oxygen.
Some here suggest the universe always existed but that's pure naturalism in the gaps. There is a lot of evidence it began to exist. If the universe always existed then time always existed and that would extremely problematic.
