Hey, um... I really need advice. I'm thinking of starting a scifi book, but I'm not sure which point of view it should be written in. It's set on another planet, where Earth(our Earth) is in a post-apocalyptic state, set in a really distant future. The main duo is a woman from a different planet, who is a doctor/scientist, and a guy who lands on the different planet from our Earth-as a last resort by the government. He's the only survivor that landed on this planet(maybe someone will join him in the future, who knows?).
Should it be in:
1.) First person point of view, from the woman's perspective;
2.) First person point of view, from the guy's perspective;
3.) Alternating first person point of view from both perspectives
