Scientific Proof Earth Hosts Life

I want a single, rigorous piece of scientific work that weighs every major dataset we currently have—exoplanet surveys, biosignature searches, radio-signal monitoring, planetary atmosphere readings—and shows, through objective analysis, that Earth remains the only confirmed home of life.

The job is to collect open data (I am thinking NASA exoplanet archives, SETI signal logs, ESA mission releases, peer-reviewed university research, and similar sources), lay out a transparent methodology, run the numbers in a reproducible environment such as Python or R, and present the results in a way that a scientifically literate audience can audit. Clear citation of every dataset and paper you use is essential; I want the code notebooks and raw outputs included so anyone can rerun the analysis and reach the same conclusion.

Deliverables
• Annotated data-gathering script(s) and cleaned datasets
• Step-by-step analysis notebook (Python/R) with commented code
• Final written report (≈15 pages) synthesising the findings, supported by charts and tables
• Executive-summary slide deck highlighting the key evidence

Acceptance criteria: methods must be statistically sound, every claim traceable to a cited source, and all files runnable on a standard desktop without proprietary software. If additional data sources beyond those named turn out to strengthen the case, feel free to work them in—as long as they are publicly accessible.
