Obama never met Reagan. Reagan died in 2004, but his last public appearance was in 1994. He suffered from Alzheimers for many years.
Obama neither God nor saint nor Devil nor Antichrist, neither was Reagan Both are/were flawed men with a vision for America. They have/had radically different ideas of how to achieve that vision. Neither got (or will get) exactly what they wanted. The US system of government works best when all sides can discuss rationally without name-calling, fear-mongering, and vitriol. It worked for years: Goldwater was great friends with Humphrey, Ted Kennedy with Orin Hatch. We've been through tough times before. Obama is president until 2012 or 2016. Focus on policy not frills. (Bush was famous for his verbal gaffes. It's not new. They aren't to be taken literally or as freudian slips.)
As to the birth certificate: do some research on the opposite side. You just might find some rational discussion. Best site: http://www.obamaconspiracy.org For instance, no one asserts that Obama was born in Ghana: the claim is Kenya. Listen to the actual tape recording of the step-grandmother (NOT his mother's sister, as Stanley Ann Dunham was an only child). The step-grandmother doesn't speak English. It's clear there was some confusion in translating the question:
Q: Was she present when he was born in Kenya?
A: He is asking her that, uh, he wants to know something that uh, was uh you, was they, was she present when, ah, he was born. Were they they there then?
Yes, they say that yes she was. She was present when Obama was born.
Q: Uh, when I come in December I would like to go by the, the place, the hospital where he is born. Uh, could you tell me where he was born? Was he born in Mombasa?
A: no, no-- what?!? No! Obama was not born in Mombasa! He was born in America!
Q: Wh-whereabouts, whereabouts was he born? I, I thought he was born in Kenya.
A: No he was born in America, not in Mombasa.
[more of this]
A: Yeah, in 1960 this was Hawaii, where his father, his father was also marrying there. This was Hawaii.
Q: Was, was, was Mrs. Obama, was sh--was she present? Was, was
Mrs. Obama, see I thought you said she was present. Was she, was, was she,
was she able to see him being, being born in, in Hawaii?
A: No, no! The, the woman was not present. She was uh not, a what--you see, she was here in Kenya, and Obama was born in America. That is, that’s obvious.
Because, because the grandmother was married here in Kenya, and Obama was born in America, oh yeah, so his son, the little Obama, was marrying, was marrying, in America, in United States.
Q: Oh, OK, fine. I mean, I--I just, I misunderstood what she was saying. I thought you said she was present when he was born.
A: No, not present there. The present with me here was tonight. Not present so she can leave. No she was here in Kenya while he, uh, her son, the little Obama, was marrying in America. And, uh, he be present if it--
WOMAN'S VOICE (background): It was in Hawaii.
A: was in America there, why are they for, theygo, they go, they go to some place, then the present isn't here sir, he was born there in America.

This has the transcript AND the actual tape of the entire call. Listen to the tape.
Note that the Grandmother seems to have gotten the question as: Were you there (in Kenya) when he was born (in America)?
16 is young. When I was 16, I was into conspiracy theories... but as a skeptic. If you learn to be skeptical of both sides, you'll do well in life.
