Yes, Earth would be visible from Mars with the naked eye. Both Earth and Mars are planets within our solar system, and if you were located on the surface of Mars, you would have the opportunity to observe Earth as a bright point of light in the Martian sky.
The visibility of Earth from Mars depends on several factors, including the relative positions of the two planets in their respective orbits around the Sun, as well as atmospheric conditions on Mars. At certain times, when Earth and Mars are favorably aligned, Earth would appear as a "morning star" or "evening star" in the Martian sky.
However, it is worth noting that the apparent size and brightness of Earth as seen from Mars would be significantly smaller compared to how Mars appears from Earth. Mars is about half the size of Earth, and the distance between the two planets varies depending on their positions in their orbits. Therefore, Earth would appear as a relatively small and distant point of light rather than a detailed and discernible planetary object.
Nonetheless, the fact that Earth would be visible from Mars with the naked eye is an intriguing concept, highlighting the interconnectedness of our neighboring planets within the solar system.
