Because Earth has so many environmental niches, so many different species flourish.

Most species of life on Earth are very small.
Protozoa, bacteria, viruses, algae, insects.
So many types, so little food and room needed for them, so many niches and eco systems and larger creatures to live within.
Large creatures (more than a pound) are facing the worst extinction period in 65 million years.

In order to come up with something good, you gotta try many recipes. Also don't forget, that only about 1% of all species are in existence at this time. 99% are gone and only preserved (if that) as fossils.

Easy answer: God
More complicated answer: Evolution and different environments cause different species to flourish
Difficult answer: It just does, no need to question it, just enjoy life and the beauty that surrounds you.
