>>7613371We can say conclusively that there absolutely positively maybe was one.
For real though science is about investigating the universe as it is not about theorizing about who put it here. If we discovered for a fact that God exists would we have to change the formulas we use to make predictions about things? Would our measurement's suddenly become invalid? No. It would be an interesting fact but it would have largely 0 impact on science.
Take these questions somewhere else. I'm not saying its a bad question or that God's existence/non-existence is not important in other ways but it is not a scientific question and the answer is not important in science.
Science seeks to understand how the universe works not why it is here or who may or may not have put it here. We want to know what the laws of the universe are, it doesn't matter if they came about by chance or were made intentionally.
