The microbes we call germs have been around for a loooong time, and, tiny as they are, they are excellent survivors. You can find traces of microbes in meteorites that have crashed to Earth from other planets and moons, on the tops of the coldest mountains, and bubbling merrily in deep sea volcanic vents. Microbes are survivors. If they "know" anything, it's how to spread and how to live in the most unlikely places.
You probably know that washing your hands after playing and before eating is a good way keep cold germs away. But, it's harder than you might think to get rid of them. If you have patient parents or a teacher, take a shaker of glitter or glitter bug lotion, and sprinkle or rub it all over your hands. Now, use some soap and water to try to rinse it ALL off. It takes a while, doesn't it, and it's hard to get it all. That's because germs, like glitter, are good at sticking to your outsides as well as your insides.
Got a sniffly nose, and need to blow? Be sure to use a tissue unless you want everybody within three feet of you to share your cold. A dripping, blowing nose is how the common cold becomes common. The germs are part of the droplets you'd blow if you didn't practice good hygiene.
Your nose isn't the only place to find germs or bacteria. Inside your intestines are e. coli bacteria that help break down your food. If didn't have these good e. coli, you wouldn't get as much energy from your meals and snacks. You've probably heard of e. coli as a kind of food poisoning that can make you very sick. While that can certainly be the case, the e. coli that's already inside you is good for you. If it gets killed off, you will have problems digesting your food.
