There isn't one single person who "supplied proof" for biogenesis. It's more accurate to say that the theory of biogenesis is supported by a vast body of evidence accumulated over centuries by many scientists.

Here's a breakdown:

* Early contributors: People like Francesco Redi (1668) and Louis Pasteur (1864) conducted experiments that disproved the idea of spontaneous generation (the belief that living things could arise from non-living matter). They showed that life only arises from pre-existing life.

* Modern evidence: The discovery of the structure of DNA and RNA, as well as the complex biochemical processes that occur within cells, provide overwhelming evidence for the theory of biogenesis.

* Ongoing research: Scientists continue to explore the origins of life through research in fields like astrobiology, abiogenesis (the study of how non-living matter may have given rise to the first life), and evolutionary biology.

So, rather than attributing the "proof" to one person, it's important to recognize the collective effort and contributions of many scientists throughout history in shaping our understanding of biogenesis.
