there is no scientific evidence to support the existence of ancient civilizations on Mars or any other planets in our solar system. All available data from space probes and rovers, such as the Mars rovers Spirit, Opportunity, and Curiosity, have not provided any conclusive evidence of past or present intelligent life on Mars.
The search for extraterrestrial life, including the possibility of ancient civilizations, remains an ongoing scientific endeavor. While some researchers continue to explore the potential for microbial life or the remnants of ancient life on Mars and other celestial bodies, no definitive proof has been found to date.
Scientific missions and future explorations, such as the Mars 2020 mission with the Perseverance rover and upcoming missions to other planets and moons, aim to gather further data and shed more light on the possibility of life beyond Earth. Until concrete evidence emerges, the existence of ancient civilizations on Mars or other planets remains speculative.
