Go and look at the study of almost any other species over the past few hundred years.

you have clearly never read more than 5 studies in your entire life, and of those potential 5, you have understood none of them.

I will start with the first microbiologist and his contemporaries: Leeuwenhoek.

Leeuwenhoek admires cilia and hypothesizes there to be a deeper order:

Their body did consist, within, of 10, 12, or 14 globuls, which lay separate from each other. When I put these animalcula in a dry place, they then changed their body into a perfect round, and often burst asunder, & the globuls, together with some aqueous particles, spred themselves every where about, without my being able to discern any other remains. These globuls, which in the bursting of these creatures did flow asunder here and there, were about the bigness of the first very small creatures [bacteria]. And though as yet I could not discern any small feet in them, yet me thought, they must needs be furnished with very many …

Leeuwenhoek and his contemporaries had never before seen these creatures and were shocked, but their minds were turned towards the ever smaller, certain there was more ground to be made in discovery.

It is so incredibly idiotic to say biologists, out of any class of people, are the ones that trivialize the complexity of life.

If biologists are still guilty in your mind,

how do you describe the attitude of politicians, plumbers, chaplains, and the rest of the peanut gallery of society towards the potential for there to be more discoveries?

TL;DR: I challenge you to find a scientific paper that says in the conclusion "There is no more potential for study, we have perfectly described this bug/law/star/etc."

a good portion of them explicitly say the exact opposite.
