Because it is efficient to organize- protozoa can only do so much organizing. You are very limited in your size if you stay a single unspecialized cell and try to group with other single unspecialized cells. You can be a mat- like the blue green algae, but your options are limited. But if you get a group of cells together and "decide" to specialize you can develop an inside and an outside. You can have a mouth and an anus (you can even BE an anus- this is extremely important to humans). You can develop nerves to coordinate your mouth and anus. You can develop structures like feet so you can take your mouth and anus for a walk. But all joking aside, there is no reason protozoa HAD to clog together and get bigger, but somehow critters got bigger- and they didn't do it all at once - BOOM (which, it seems to me, would be the way an efficient God would do things- if he really was all powerful)- they did it slowly, and as you progress up the Phylum toward the chordata you see the organization of the creature add layer upon layer of complexity- and to me chance, or bits of starter fluid from a comet are just as likely or more likely than a prime mover. So one protozoa is lying next to another protozoa, they are differently adapted protozoa- and the one swallows the other but the other protozoa perhaps has an adaption that keeps it from being digested- suddenly you have a critter with another critter inside it. If these two one celled organisms do different things then you have basically a new organism with two cells functioning- and if those cells become coordinated, and can reproduce themselves, perhaps they find they have advantages over the one celled organisms. So why get bigger? To better exploit. Did they have to get bigger? I don't see why. Did organisms get bigger? I would say all the evidence points to yes. Do we know why absolutely? No. Have I ever seen any evidence that God had anything to do with it? No.
