This thread is on the subject of scientific evidence, though. Evidence cannot be considered scientifically unless it is verifiable. So, circumstancial evidence cannot be considered.There are all kinds of evidences. Just as you can be sent to death row because of evidence that show beyond a reasonable doubt on forensic tangiable evdience you can also visit old smokey due to an overwhelming amount of circumstancial evdience. Sadly, many atheists etc only allow evdience of their choosing to consider as valid. That is wrong but typical failings of debating in good faith.
