The oldest evidence of life in the galaxy was discovered by the Kuiper Serendipity exploratory science vessel in 2334. Frozen for eons, the single-celled organism was buried deep in the ice-asteroid KI34J39 and was found through routine water purification.
The unicellular organism is now located in the science museum of Luna. More information can be found here: https://www.voice.com/creation/100000000024310
