Why should I admit the falseness of other miracles? Jesus told his apostles they would do the same works he did. Jesus did not replace amputated limbs, but did raise the dead and heal the sick.
When I was a Christian I thought I could feel the unique holiness of every place I visited. I reveled in the feeling, but never once heard anything or anyone actualy speak to me. I am still quite convinced the feeling is real, but the consistant lack of tangible evidence has long sense lead me to ask myself whether beliefe in God is essential for it.
People can "feel the unique holiness" of places without believing in God. As to tangible evidence:
Matthew 12:38-42
Then some of the scribes and Pharisees answered, saying, "Teacher, we want to see a sign from You."
39 But He answered and said to them, "An evil and adulterous generation seeks after a sign, and no sign will be given to it except the sign of the prophet Jonah. 40 For as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth. 41 The men of Nineveh will rise up in the judgment with this generation and condemn it, because they repented at the preaching of Jonah; and indeed a greater than Jonah is here. 42 The queen of the South will rise up in the judgment with this generation and condemn it, for she came from the ends of the earth to hear the wisdom of Solomon; and indeed a greater than Solomon is here.
