Do not want to nitpick your words, but can you elaborate on why you put unscientific and intelligent design close to each other? I think you wanted to say intelligent design is not scientific, right?
Just watched this video today related to concept of fine tuning in cosmology: https://www.youtube.com/watch?v=oaVlTIymQ3g
Today's scientific facts/theories mean, here are things we learned based on our observations and things we knew from the past, but some answers are still not definitive, especially when it comes intelligent design, fine tuning and multiverses. People thought Newton was right, until Einstein came up with different theory, who knows what next Einstein proves how we were wrong.
