Yes, if you've read this thread and understand it, you would see how what you ask is out of place and has been debunked in great detail.
I want to give the benefit of the doubt, but it "could mean" 1st chronological in order or reading order for an appearance?
And the world for that? Is called an "origin issue!" That doesn't make it chronological in real world appearance, except Spider-Man finding the symbiote firstly in sw8 that is just an origin issue. Meanwhile people who read symbiote issues in the real world had months full of seeing an symbiote appearance before sw8. Lol
It's bewitched how it always gets advertised as a 1st, because it is an origin people get confused? idk. That is the Only way "I can understand" to put it straight every time I read it
