Was Darth Vader Realy Luke Skywalkers Dad?

One problem with you new nairalanders is that u have a habit of posting topics in the wrong section. Post this topic in the general discussion or offtopic section because this has got nothing to do with religion. IDIOT!

May the Force be with you my brothers.  Yes Luke's mom might have had an affair but it seems that Darth Vader was her first time from the records available.  Now what are the proofs of Luke's paternity.

1) He inherited a great amount of the Force.  The only other person in whom the Force was that strong was Darth Vader.  It is unlikely that Luke got his propensity from another person because there was no one else with that level of propensity.

2)  The Force would have told him otherwise if it were not the case.

3)  Why would Luke want to make it up?  That would make him Princess Leia's brother and I'm sure finding that out was a bit of a let down for him.  I coulda sworn that up until that point Luke and Leia's connection was heading in a conjugal direction.  I can only imagine that Luke would be unhappy to find that all his fantasies up until that point were in actual fact incestuous.
