Bro, this will not be my original idea.
Based from some theists apologist, the age and size of the universe is just right for the emergence of life. In other words, the universe is finely tuned to the most exact values for life to occur. We are not the product of accident or blind-random interaction of matter. Random combination of matter for life to occur with respect to the age and size of our universe is beyond probability. So they say hence, if life occured in our universe randomly, it would be ridiculous for this random process surpasses that of our own universe's age.
Meanwhile, sa ngayon, ang alam natin ay earth lang ang may buhay. So, your question is relative to contemporary scientific findings. What if in the future may nadiskubre na buhay sa ibang planets or even life not of organic materials? Would that prove or disprove the existence of God? Your question is scientifically interesting per se even not to drag the God question.
Maliban diyan, what if humanity will survive thousands of years from now and able to penetrate or create multi dimensional realities? What if humanity survived billions of years from now that it will be able to transcend the physical universe or space and time to re creat past realities? What if hamunity survived thousands, millions, billions, trillions, quadrillionons, gazillions of years from now that humanity equals infinity equals the God from the infinite future where this present is just memory from the timeless life of God? I do not know? From practical and pragmatic points of view, theism and/or atheism seem matter to some individuals. However, if we were talking here of time in terms of thousands, millions, billions or even infinity in the future, the arguments or beliefs no longer matter.
