1. 1. Radial Velocity
2. Astrometry
3. Transit Method
4. Optical Detection

2. I mostly understand Astrometry the most because it is a method to learn about planets further out in space. Like, when you measure a star distance from another star and put it in measurement formulas, you will discover it's masses, gravitational pull, and if it is closer or further away.

3. Goldilock Zone is a area where life is said to be substainable for human life. If it is not too hot or too cold then its theorized that water might be on these planets.

4. A. I think their life forms might be more advance than our lifes but then again our life forms might be more advanced than their. It looks more greener than our planet.
B. They might tend to be more aggeresive towards us because we are new life forms and to them, we are unknown in a known territory.
C. They might be smarter than us or we might be smarter than they are. but because we are going to their planet, they will be smarter than us because they know their planets better than we do. Same with us about our planet if they were coming to earth.

5. I do believe their are other life forms just like us but they are not aliens. Becuase if we call them aliens, then through their eyes, we are the aliens. There are multiple galaxies outside of our own, and if we have a livable planet in this galaxy, than theirs possibly another livable planet in other galaxies. We shouldn't feel like we are the most supier specie because out their we don't know nothing out their and for them they might not know nothing about us or this solar system.
