But that's the great thing about science.

We can come up with amazing new ideas about how the world operates, based on empirical evidence and analysis.

We can admit that we are unsure about some parts of theories, or that there seem to be "missing pieces" that make us doubt.

But later on in time somebody else may make a new discovery that causes everything to make sense.

Such is the example of the later discovery of genetic inheritance supporting natural selection, along with new discoveries about the Earth and how it goes through changes that take place over very long time scales, which helped support the idea of slow evolution over time -- in contrast to a more prevalent "young Earth" hypothesis.
