Maybe the hole was made for the puddle, who’s to say it wasn’t? Perhaps a large number of coincidental occurrences made it, but there sits the water in a hole that perfectly accommodates it. Something that the people who built the road expected. How can one say it wasn’t the intention of the organization of the universe in a series of probabilities that one day that water would be right on that puddle, in a specific moment in time? Wouldn’t that arguably make the hole made for the water at that point in time ?
I guess that’s more of a philosophy debate, but honestly until we get more data, it could be anything. All we know is that our long range scanners have not detected advanced civilizations and that doesn’t match our expectations. It could be because they don’t exist, it could be because they’re hiding themselves from us.
We know very little about alien life at this point and until we have more information, every explanation is possible. Some scientific explanations of the universe or life that were eventually discovered were certainly more wild and vivid than we previously thought before. I’m not saying this is what is necessary happening, just something that could be happening.
