Is there any strong support that shows miracles actually happen? 

Yes agreed, our experience of human nature tells us that people are prepared to lie for gain. What is less likely, when it comes to the miracles of Jesus, is that the evangelists were prepared to lie for trouble and eternal damnation. Thus their suffering becomes the powerful evidence that they at least, were telling the truth about the miracles of Jesus Simon Greenleaf, who was an atheist professor of law that wrote 'the rules of evidence' for the American court system back in the 1900's was challenged by his students to apply his rules to the new testament. He did and converted to Christianity as a result. He wrote a short book called 'testimony of the evangelists' to explain his reasoning. Quote And first, as to their honesty. Here they are entitled to the benefit of the general course of human experience, that men ordinarily speak the truth, when they have no prevailing motive or inducement to the contrary. This presumption, to which we have before alluded, is applied in courts of justice, even to witnesses whose integrity is not wholly free from suspicion; much more is it applicable to the evangelists, whose testimony went against all their worldly interests. The great truths which the apostles declared, were that Christ had risen from the dead, and that only through repentance from sin, and faith in him, could men hope for salvation. This doctrine they asserted with one voice, everywhere, not only under the greatest discouragements, but in the face of the most appalling terrors that can be presented to the mind of man. Their master had recently perished as a malefactor, by the sentence of a public tribunal. His religion sought to overthrow the religions of the whole world. The laws of every country were against the teaching of his disciples. The interests and passions of all the rulers and great men in the world were against them. The fashion of the world was against them. Propagating this new faith, even in the most inoffensive and peaceful manner, they could expect nothing but contempt, opposition, revilings, bitter persecutions, stripes imprisonments, torments and cruel deaths. Yet this faith they zealously did propagate; and all these miseries they endured undismayed, nay, rejoicing. As one after another was put to a miserable death, the survivors only prosecuted their work with increased vigor and resolution. The annals of military warfare afford scarcely an example of the like heroic constancy, patience and unblenching courage. They had every possible motive to review carefully the grounds of their faith, and the evidences of the great facts and truths which they asserted; and these motives were pressed upon their attention with the most melancholy and terrific frequency. It was therefore impossible that they could have persisted in affirming the truths they have narrated, had not Jesus actually rose from the dead, and had they not known this fact as certainly as they knew any other fact. If it were morally possible for them to have been deceived in this matter, every human motive operated to lead them to discover and avow their error. To have persisted in so gross a falsehood, after it was known to them, was not only to encounter, for life, all the evils which man could inflict, from without, but to endure also the pangs of inward and conscious guilt; with no hope of future peace, no testimony of a good conscience, no expectation of honor or esteem among men, no hope of happiness in this life, or in the world to come.

Hi, thanks for your comment. Three things to consider: first, even if some miracle stories are lies, a false miracle doesn't invalidate a true one any more than a counterfeit dollar invalidates genuine money. What I want to demonstrate is that some miracles can and do happen, which points toward the God that performs them. Second, lying assumes people have motives to tell untruths. But many if not most people who testify to miracles have nothing to gain by this deception. Sure, there's the odd few who try to turn their experience into a business model. But most have much more to lose than to gain in terms of reputation. Third, lying becomes a difficult or impossible explanation when the evidence isn't reducible to word of mouth testimony. The first and third categories of evidence, for example. What do you think about that?
