Quote from OPTIONAL777:
Correct, I don't know.
Do the facts at hand indicate he was born in the USA?
Yes, the facts do indicate that.
Who knows?
The doctor, the mother, the attending nurses know someone was born.
Could Obama be a brother from another planet?
I don't know, possible.
Could Obama be an impostor?
I don't know, possible.
If someone presents a birth certificate is that absolute proof and knowledge that they were born somewhere specific place and time?
Nope, the document could be forged.
Actually knowing something is terribly limited to senses and logic.
Most of what people claim to know is second hand information, and simply a strong belief or trust in the person or institution professing knowledge.
Of the facts available, I see no evidence that leads me to doubt Obama is not a US citizen.
Of course, I'm not a big fan of conspiracy theories, because statistically, they are so often wrong....and examination of the screwballs who do believe them lends greater support to the conspiracy theory being absurd.
Try to answer one question:
If an appropriate (in your opinion) birth certificate surfaces, how will you know that it is not a fake?
