I stated why it is. You have not offered any reason to discount that argument.
Think of it this way: The universe is just information. The present location, spin, energy level, etc. of all of the quarks that make up your body could, in theory, represented as a set of recorded data. This is also true for the Earth, it’s atmosphere, etc. Now assuming that quarks act according to some physical rules which we can simulate, we could take the previously attained set of data and use it as the dataset for a simulator which knew nothing more than how to cause virtual quarks to act like our universe’s quarks and we would have a fully functional Earth, including all of its life, at the complete level of intelligence as all of the real world life that exists on the Earth.
This requires is an amazing quantity of processing power and a really impressive scanning device, but nothing more a simple quark interaction simulator.
Now I don’t think that that’s necessary for us to create life. But it’s a proven fact that matter-like-substance in the presence of physical laws, given enough time, can spontaneously create life and that evolutionary forces can cause that life to gain intelligence. Using a bit of creativity, we can focus that process a lot more, like by replacing matter with cuboids and replacing the atoms of a brain with high-level software neurons, and so reduce the total amount of processing power and data that is required, but fundamentally you’re doing the same thing. You’re not creating AI, you’re creating an environment that allows AI to come into existence.
