Without bacteria, life on earch would not exist. They are all part of the essential cycle of life. Yes: some are annoying! But most are helpful.
For example, bacteria even support a complete eco-system in the total absence of light! Thousands of feet under the sea – at such a depth that no light can penetrate – bacteria make it possible for other micro-organisms and fish to exist.
How do these bacteria live? They use the energy derived from breaking down sulphur compounds, rather than by using oxygen. Sulphur would kill the rest of us, but these bacteria thrive.
