If ifs and ands were pots and pans, then there'd be no work for tinkers' hands.

It means that it's pointless to sit aroung and wish for things (usually when someone says If______I would be so happy) The whole saying is 'If ifs and ands were pots and pans there would be no work for tinkers hands'. Tinkers are nomadic people who used to earn money by repairing worn out pots and pans.

If pots and pans were "if s & and s" there would be no need for tinkers.

If "ifs" and "and"s were pots and pans, there would be no need for tinkers!. That saying sums up the answer - Henry VIII did exist and speculation as you suggest is essentially a wast of time.

I think so.
