Hi, I come from a very Catholic family but never really believed in God. I slowly took distance from religion and now I’m exploring atheism.
Recently found a video about how the “fine tuning” argument was one of the more difficult for atheists to answer.
But thinking about it the argument is the same theists apply when they don’t know the origin of something. Since the origins of humankind, we always filled the gaps of the unexplained with the supernatural, specially when there’s an apparent order or improbability in this case.
Science might not know why the universe is like it is, but the improbability of it doesn’t prove intelligent design.
Edit: Thanks for all the answers, very good points in the comments, and sorry I’m replying so late and didn’t explain what the argument is:
The fine-tuned universe is the hypothesis that, because “life as we know it” could not exist if the constants of nature – such as the electron charge, the gravitational constant and others – had been even slightly different, the universe must be tuned specifically for life.[1][2][3][4] In practice, this hypothesis is formulated in terms of dimensionless physical constants.[5]

The fine tuning argument is just the Texas sharpshooter fallacy dressed up in fancy language, requires either grossly misunderstanding or willfully misrepresenting the fact that it’s using the conclusion to form the premise. The Earth isn’t perfectly “tuned” for life to evolve on it. It’s actually the other way around: Life evolved on Earth to fit the conditions here.
And, lots and lots of types of life on Earth died out over the aeons as conditions here changed, with new life having to evolve to fit the subsequent conditions. See, for instance, the oxygenation catastrophe. If god really had a plan for every beast of the land and fish of the sea to fill its niche from the beginning, why have so many of them already gone extinct?
Arguing about the apparent improbability of life developing on this planet is a silly notion coming from the point of view of life that’s already developed and evolved on that same planet. People who insist on that should try doing so on one of the billions upon billions of other planets in the universe where life didn’t develop instead. It’s like trying to explain to someone who’s already won the lottery that, acktshully, winning the lottery is totally mathematically impossible so therefore they didn’t. The balance of their bank account notwithstanding.
