I don't make the claim that we haven't done it yet is a reason we will never do it.
You did say:
All we can say is "maybe one day we'll figure it out". But that's just one of those coin phrases to put off the reality of human limiation.
A phrase to "put off the reality of human limitation" seems fairly interpreted as "an excuse we make to ourselves because we won't ever be able to do i." How else would you mean it? Because you could just say "maybe one day we'll figure it out" without the weak sauce interpretation if that's what you meant.
Ironicallty, this is an argument a number of people use to suggest the Bible is fiction. "We don't see evidence of King David's or Solomon's kingdoms, therefore they never existed".
"We do not see evidence for X, therefore we don't believe X." This is as simple as it gets. And if you're talking to people who are keying on the existence of kingdoms as to why the bible is rightly classified as fiction, they're missing the forest for the trees. Exhibit A: light before stars. Exhibit B: Noah's Ark. Exhibit C: Moses tale. The list continues. Your thinking would say "just because we've ever seen light exist without stars, we can assume we just don't know how it works, therefore it's probably possible," or something like that.
Are you claiming that anything other than complete unconcious existence after death means "magical afterlife"? If it's something that science doesn't (at the moment) touch a concious afterlife, it would have to be magic?
It's not unconscious existence. It's not existing anymore. Are you proposing that there IS a magical afterlife? Cool, what evidence can I examine to determine it's definitely there, as you have? Yeah, I'm calling it magic.
Rather, it's impossibly possible. I don't rule out the possibility of producing sentient life, but in my opinion the creator has rendered it impossible.
We're sort of back where we started: how did you arrive at this opinion? Because it sounds like nonsense.
Would it be moral? This question gets posed in a number of fictional writings like "Frankenstein", where the question comes along "should we play God"?
That isn't actually the question of the book Frankenstein's Monster. The question in that book is if you did it, what do you owe to it? For example, if you could create sentient life, would it be moral to create it with the full knowledge that you were going to torture it for a really long time just for your own amusement? Would you owe it free will, the ability to love? What would it owe you, would it be moral to keep it as a slave? Would it have to do as you bid under fear of bodily punishment?
When it comes to questions of the afterlife, I think the most atheistic of atheists understand that this is much deeper than creating healthy energy drinks. It would present a challenge to deityship, therefore has appeal as the idea tantalizes us with proving the non-existence of an ultimate creator of divine nature.
??????? This is word salad. I'm glad to address if you can clarify what you're trying to get at. What's it have to do with sentience?
