Not thoroughly understanding consciousness doesn't mean we can't create it. All sorts of phenomena are created without an understanding of the underlying mechanism. The entire animal kingdom, including us humans, have been creating conscious beings (babies) without understanding how consciousness actually works.

Of course, understanding the mechanism is helpful if you want control, reliability, and precision over the phenomena, but creation can definitely happen before we can explain it.

Seems like the entire field of alchemy and later chemistry was precluded by a "oh wow" or "that's interesting" or "help, I can't breath", not derivations from first principals. Throwing stuff together just to see what happens and then working backwards from interesting outcomes to recreate and understand those interesting outcomes seems like a perfectly valid if not chaotic approach for happening upon artificial consciousness.
