Evolution made a conscious mind (or something which perfectly mimics a conscious mind) out of atoms. So it's an engineering problem not science fiction for humans to do it.

Agreed. That’s also what the Church-Turing thesis says, and I believe it. We aren’t based on magic, therefore we could build something also not based on magic. Though it’ll likely not be built by us, but perhaps evolved by us.

I’d say human level AI is possible now with current tech, we just don’t know how to create the software. That might take another 20 to 1,000 years.
