Bill,
I really don´t understand you.
This forum contains well educated people of many trades and professions.
If you ask a polite question you are almost certain to get an excelent answer, by elaborating you can get it explained to your level.
Why don´t you try to throw off the truther mindset and learn.
This is the place to do it.
Those strange people who insist, bizarrely, on calling themselves "truthers," although they do little apart from telling lies, cannot learn. They can't admit any errors or make any concessions, however slight. Their incredibly stupid myths can't survive any contact with reality.
