I found this site which might be of help:http://www.jesuschristislord.net/exist.html
1. Everyone believes in something. No one can endure the stress and cares of life without faith in something that cannot ultimately be proven. Atheists cannot prove there is no God. Pantheists cannot prove that everything is God. Faith is unavoidable, even if we choose to believe only in ourselves. What is to be decided is what evidence we think is pertinent, how we are going to interpret that evidence, and who or what we are willing to believe in. Read (Hebrews 11:1-6)
2. Scientific method is limited to a process defined by that which is measurable and repeatable. Science, therefore, has great potential for both good and evil. All science can do is show us how natural law works, while telling us nothing about its origins Read Job 26:7-14; Eccl. 1:13-17. Luke 11:52;
3. Some have assumed that an evolutionary explanation of life would make God unnecessary. This overlooks some problems. Even if we assume that scientists will someday find enough "missing links" to confirm that life appeared and developed gradually over great periods of time, laws of probability would still show the need for a Creator (i.e. intelligent designer) Read (Romans 1:20) and (Hebrews 11:3)
4. Mankind has been described as incurably religious. In unguarded moments of trouble or surprise, in prayer or in profanity, references to deity persist. Read (Ecclesiastes 3:11). There is something about truth, beauty, and love that makes our hearts ache. Even in our anger with a God who would permit injustice and pain, we draw upon a moral conscience to argue that life is not as it ought to be (Romans 2:14-15). Even unwillingly, we are drawn to something that is more rather than less than ourselves.
5. On first reading, the opening words of the Bible seem to assume the existence of God. Genesis, however, was written at a point of time in history. Moses wrote, "In the beginning God" after Israel's exodus from Egypt. He wrote after miraculous events that were said to have been witnessed by millions of Jews and Egyptians. From the Exodus to the coming of Messiah, the God of the Bible rests His case on events witnessed in real time and locations. Anyone who doubted the claims could visit real places and people to check out the evidence for themselves.
6. Israel is often used as an argument against God. Many find it difficult to believe in a God who would be partial to a "chosen people." Yet from the beginning of Old Testament history, Israel's future was prewritten. Together with other prophets, Moses predicted not only Israel's possession of the land but also her unparalleled suffering and dispersion throughout the whole earth, her eventual repentance, and then finally her last-days restoration (Deuteronomy 28-34; Isaiah 2:1-5; Ezekiel 37-38).
7. Many who doubt the existence of God have reassured themselves with the thought, "If God wanted us to believe in Him, He would appear to us." According to the Bible, that is what God has done. The prophet Isaiah said that God would give His people a sign. A virgin would bear a son who would be called "God with us" (Isaiah 7:14; Matthew 1:23). Isaiah said this Son would be called, "Mighty God, Everlasting Father, Prince of Peace" (Isaiah 9:6). The prophet also said that this child would die for His people's sins before seeing His life prolonged and honored by God (Isaiah 53). According to the New Testament, Jesus claimed to be that Messiah. Under the oversight of a Roman governor named Pontius Pilate, He was crucified on charges that He claimed to be the king of Israel and that He had represented Himself as being equal with God (John 5:18).
8. The reports of the first followers of Jesus agree that He did more than just claim to be the long-awaited Messiah. These witnesses said He won their trust by healing paralytics, walking on water, and then voluntarily dying a painful, undeserved death before rising from the dead (1 Corinthians 15:1-8). Most compelling was their claim that many witnesses had seen and talked to Christ after finding His tomb empty and before watching Him ascend visibly into the clouds. These witnesses didn't have anything on earth to gain by their claims. They had no hopes of material wealth or power. Many became martyrs, claiming to the end that the long-awaited Messiah of Israel had lived among them, that He had become a sacrifice for sin, and that He had risen from the dead to assure them of His ability to bring them to God.
9. Some who believe in God do not take His existence seriously. They reason that a God great enough to create the universe would be too big to be concerned about us. Jesus, however, confirmed what the design and detail of the natural world suggest. He showed that God is great enough to care about the smallest details of our lives. He spoke of one who not only knows every move we make but also the motives and thoughts of our heart. Jesus taught that God knows the number of hairs on our head, the concerns of our heart, and even the condition of a fallen sparrow (Psalm 139; Matthew 6).
10. The Bible says that God designs the circumstances of our lives in a way that will prompt us to look for Him (Acts 17:26). For those who do reach out for Him, the Scriptures also say that He is close enough to be found (Acts 17:27). According to the apostle Paul, God is a Spirit in whom "we live and move and have our being" (Acts 17:28). The Bible makes it just as clear, however, that we must reach out for God on His terms rather than our own. He promises to be found, not by just anyone but by those who admit their own need and are willing to trust Him rather than themselves.
You're not alone if you are open to the existence of God but aren't sure you can accept Jesus' claim to be "God in the flesh." The teacher from Nazareth promised help to those who are concerned about doing the will of God. He said, "If anyone chooses to do God's will, he will find out whether My teaching comes from God or whether I speak on My own" (John 7:17 NIV).
If you do see the evidence for the God who revealed Himself to us through His Son, then keep in mind that the Bible says Christ died to pay the price for our sins, and that all who believe in Him will receive the gifts of forgiveness and everlasting life. The salvation Christ offers is not a reward for effort but a gift to all who in light of the evidence put their trust in Him (John 5:24; Romans 4:5; Ephesians 2:8-10
