yeah.. but god doesn't want to prove his existence to us, he wants us to have free will to believe what we want.
Why, Yorda, did Jesus perform miracles? Just for the fun of it? Again, your claim that "god doesn't want to prove his existence to us" because of free will is completely wrong.
Jesus performed miracles to HELP people believe in him. He didn't MAKE people believe in him, that's impossible with free will. Instead, he helped them out a lot by doing many amazing things which deny physics and which, to me, constitute good evidence and would probably convince me of God/Jesus as well.

John 1:45-49
45 Philip found Nathanael and said to him, "We have found Him of whom Moses in the law, and also the prophets, wrote--Jesus of Nazareth, the son of Joseph." 46 And Nathanael said to him, "Can anything good come out of Nazareth?" Philip said to him, "Come and see." 47 Jesus saw Nathanael coming toward Him, and said of him, "Behold, an Israelite indeed, in whom is no deceit!" 48 Nathanael said to Him, "How do You know me?" Jesus answered and said to him, "Before Philip called you, when you were under the fig tree, I saw you." 49
Nathanael answered and said to Him, "Rabbi, You are the Son of God! You are the King of Israel!

John 2:18-22
18 So the Jews answered and said to Him, "What sign do You show to us, since You do these things?" 19 Jesus answered and said to them, "Destroy this temple, and in three days I will raise it up." 20 Then the Jews said, "It has taken forty-six years to build this temple, and will You raise it up in three days?" 21 But He was speaking of the temple of His body. 22 Therefore, when He had risen from the dead,
His disciples remembered that He had said this to them; and they believed the Scripture and the word which Jesus had said.
God/Jesus proves his existence to the disciples.
So, Yorda, did these thousands of people Jesus performed miracles in front of lose their free will? I don't think so.
If God/Jesus doesn't like proving his existence to people, he really acted strangely in the instances mentioned above (and the hundreds of miracles that weren't written in the Bible).
