I need some one to prove that the solar system exists?

take this person to an observatory.

Just ask that someone if she has ever seen stars. Or does she think the sky is a black blanket and the stars are shiny glitters?

Show them that its the best explanation we have so far. If this person looks up at the night sky and insists they are seeing a big blanket with little holes poked in it, there's not much hope for them. Ask them what's behind the blanket. The best proof is knowing where certain stars/planets will be at what times of year. Astronomers have gathered this information over ages and improved our perception to the point of understanding it better.

well the solar system does exist, if it did'nt you or anyone would'nt have existed, there are also other solar systems out there millions/billions trillions of miles out there. tell that to that someone.

other planets are visible from earth. do you have a planetarium or science center or big telescope in your city? even a small telescope will show you some planets in our solar system.

show that person the photos of the planets taken by space crafts, be sure to show them how earth looks like from space as this will give them a perspective of how tiny we are. Rather then buying a telescope take that person to the nearest observatory as they have really big telescopes and the planets actually look something like u see in the photographs from spacecrafts

microscope er i mean telescope.. or get pics or something

Nicolaus Copernicus did this 500 years ago. http://en.wikipedia.org/wiki/Nicolaus_Copernicus

well um get her a telescope and check out mercury or venus they are practically visable with the naked eye but much better viewed by telescope.... hope this helps
