Because that would need proof that says that "inventing" the cellcore is an extremely unlikely event in organisms. (but I have never ever heard anyone claim that)

The sheer unlikeliness of that happening is staggering. The fact that we had prokaryots for a billion years (according to Wikipedia) before we had Eukaryots should tell you how unlikely it is. It's not like there were much fewer bacterias around then. The major theories always starts with a bacteria however, which is kinda the antithesis of your argument. Bacteria evolving into eucaryotes, evolving into multicellular organisms.
So when you say "Why hasn't bacteria evolved into multicellular beings?" my answer would be, "They did". And the answer to the question "Why can't we see that happening with bacteria today?" would be "We're not looking closely enough".

"The fact that we had prokaryots for a billion years (according to Wikipedia) before we had Eukaryots should tell you how unlikely it is." - doesnt prove anything for me. It's other way around. Knowing what I know about bacteria makes it impossible for me to think there was 1 billion years between pro- and eukaryotes.
So when you say "Why hasn't bacteria evolved into multicellular beings?" my answer would be, "They did".
- yes yes, do u think I missed that there exists multicellular organisms? That the two lines split? That's just looking at the problem from another angle, or rephrasing it. Why did it only happen once (knowing that the bacteria kept being widespread and successful for 100s of millions of years)?

Maybe there's too much competition for it to happen again? It only needed to happen once, and now maybe there are more complex organisms better at doing what the new guys try to do?

That's a basic, mandatory question that has to be asked of course, and has to be answered.
It's not satisfying in this case though. Bacteria are too many, too competitive in so many ways. That argument can be used, the argument about niches and competition, in many cases (such as the giraffe has a long neck so he eats all the high leafs etc, so the antilope never got a chance to really compete with the master giraffe, therefor antiliopes and shit dont have long necks) but bacteria is a different case because the scale is so extreme. Just think about it, you have 10 pounds of bacteria in your body at any given moment. Those guys are everywhere.
