Lol, philosophical disagreements are the best!!
From a sceintific standpoint you would have the burden of proof, that is, you have to prove that what you’re saying is 100% accurate. As of now, yours remains a theory; it’s based on some strong evidence (based on probability more than anything else), but it remains a theory nonetheless. Even the famous Wow! Signal (
https://en.m.wikipedia.org/wiki/Wow!_signal) could be used as evidence somehow... but it would’t be enough. We need certainty, which is something we don’t have at this moment. My understanding is that life, for what we know, is very very difficult to begin, and it’s even more difficult for it to evolve. A single degree in temperature might make the difference between a cell that will become the mightiest civilization of the universe and a dead, undeveloped form of life. Considering all the other factors (oxygene, CO2, methane, radiations, etc.) mixed with the time necessary for going from cell to sentient being, I am not overly optimistic or overly pessimistic. We’re at the beginning of our understanding of the outer universe.
Although I am religious myself (Catholic), I have absolutely no objection to the possibility of God creating other worlds; heck, I certainly don’t understand why the heck He would’ve created this messy world, so speculating on God’s desire to create (or not) other forms of sentient life would be proposterous on my side...
