Based on the eventual destruction of the solar system and the critical need for human continuation, as well as humans cannot travel to the nearest habitable exoplanet within a lifetime, this article suggests sending synthetic biology- and AI-created plant-like astronauts to the closest habitable exoplanet. These astronauts have green skin, blue blood, and the ability to perform photosynthesis. They can withstand cosmic radiation and extremely low temperatures in space, while generating energy through photosynthesis. This interdisciplinary approach may offer a solution for the survival challenges faced by humanity during its eternal interstellar exploration. As long as these plant-like astronauts possess human consciousness, it is irrelevant whether they are hybrids of carbon- and silicon-based life forms. They will continue their lineage of humanity on exoplanets. Humanity has two survival options. The first option is the Martian migration program led by Elon Reeve Musk, which is both visible and realistic. It could provide an immediate option for human continuation and expansion, although it may not help us escape the future burning of the Sun during its red giant. The second option involves directly sending plant-like astronauts beyond the solar system. This kind of audacious adventure may be worth it: escaping its destruction entirely and preserving our species. Instead of struggling on Mars for thousands of years to reach today’s technological level on Earth and then initiate an “escape from Mars”, it may be more feasible to begin the “escape from Earth” to Teegarden’s Star b now. Should we consider both options simultaneously, much like how humans use their two legs to walk? We must strive with all our might; otherwise, humanity will forever be trapped within the solar system, awaiting the inevitable helium flash to come…
