Don't worry, we know you wasn't there, but since you are so sure you must have good, falsifiable evidence. Might we see it?
Hedshaker, thank you for your invitation such as I understood it to be. I thought about a response overnight. You may have been thinking about evidence for a YEC position and I have been inclined toward such a position but have been open to other POV's that can be reconciled with Genesis 1 and the overall Bible. Shown below is a partial summary combining notes that I wrote a few years back and new content added today to justify belief in the existence of God.
Why I Align My Life With Belief In The Existence of God
Matter and Energy Exist; Life Exists - There are only two ways this could have happened. 1) Matter has always existed; 2) God brought matter into being.
Nature and the universe have order. Gravity is predictable. Atoms, ions and electricity behave in predictable ways. Tides and eclipses can be predicted years in advance. The earth's axis tilt, rotational speed, orbital speed, distance from the sun and moon are all balanced with exquisite precision; the human body has amazing properties and order. Without all of this, life as we know it could not exist. Your weight on Jupiter would be two and one half times what it is on earth because of the immense size of Jupiter. God is the author of order and balance.
Uniqueness of the Bible and Jesus Christ - 40 Authors over 1500 years wrote the Bible with remarkable beauty, accuracy, and harmony. Jesus Christ spoke words and performed works like no other. Jesus is unique in human history. Many aspects of the life of Jesus Christ were prophesied hundreds of years earlier. Other aspects of Bible prophecy remain to be fulfilled in the future. There is a beauty and excellence and influence that emanated from the life of Jesus Christ like that of no other.
Human beings have an understanding that horses, lizards, birds, and fish do not have. Although it is often suppressed, human beings have a conscience. By conscience, human beings know something about right and wrong and sense that they may eventually be held accountable. Christian catechisms maintain that human persons possess souls that will never die.
Eternity in heaven or hell are vast concepts and too important for anyone to gamble on the outcome. Since there is evidence of intentional Creation; human beings have an obligation to thankfulness and to seek out their Creator. The Creator has no obligation to reveal himself to our senses of sight, hearing, smell, taste and touch. Evidence has helped detectives to resolve investigations but God is powerful enough to create without leaving behind a trail of evidence (Hebrews 11:3). God does call us to repentance, faith, hope, and love.
Without a final Judgement, many injustices done in the world will never be corrected. Only through what the one Redeemer, Jesus Christ, has accomplished can God righteously demonstrate both full, severe justice upon some and everlasting mercy upon others. Note: The Bible does teach degrees of punishment in the place of darkness and degrees of reward in the place of light.
Other Arguments
Beyond the Five Senses - Naturalists believe that everything that can be known begins with observation by the five senses of sight, hearing, taste, smell and touch. Already, there are electromagnetic realities that we can observe only with instruments such as invisible light, cosmic background radiation, neutrinos, sub-atomic particles, etc. Mankind has no good way to know what we may be missing and have not yet observed. The Creator can warp space and time.
Justice - Rewards and Punishment - If there is no God, no Judgment, no Redemption, then there will be no correction of injustices done against and by those who have passed on and are no longer alive. If no after life and accountability, then there will be no punishment for wicked deeds done and no rewards for righteous deeds.
Symphony analogy - Symphonies have composers and conductors who bring about purpose and order. Likewise, the universe has a composer (Creator) and conductor (Sustainer) who manages purpose and order, beginning and ending.
Changed lives - Christian martyrs from Steven (Acts 6-7) to the early century martyrs of the Roman Colosseum and catacombs to the many Christian martyrs since then have shown love for Christ and faithfulness unto death.
Changed lives - Drug addicts - In our generation, there are cases where Christian ministries have enjoyed remarkable successes in bringing people through deep drug addictions into productive, Christian lives without drugs. I know someone from that background with that type of story.
Changed lives - The lives of William Wilberforce (1759-1833) and John Newton (1725-1807) are remarkable stories. I recommend biographies of either. The genre of Christian biography has many excellent stories to tell.
Changed lives - Amy Carmichael (1867-1951) was a Protestant Christian missionary in India, who opened an orphanage and founded a mission in Dohnavur India. She served 55 years in India and never married and never returned to Ireland. The legacy and impact of her work continues to the present time.
Changed lives - Christianity has produced wonderful examples of changed lives and lives of extraordinary dedication. Love is a wonderful thing. Christianity has produced wonderful examples of love, patience and kindness among people in both prominent and humber circumstances throughout its existence. Hospitality, healthcare, education, poverty outreach and social justice causes like the anti-slavery movement are just some of the places where Christians have served. Not all professing Christians have been loving and some professing Christians have surely hypocrites but many have been genuine and sincere.
Jesus Himself - Jesus lived in humility and poverty when He came the first time. Jesus has influenced history and lives for the good like no one else. At his first coming, Jesus did not command wealth and armies and did not acquire glories and honors. Jesus accomplished redemption of guilty sinners by living a sinless live and suffering as an innocent man on behalf of others. Jesus rose from the dead and will come again in a display of great glory and might. The miraculous works of Jesus Christ in healing, turning water in wine, walking on the water, feeding the multitudes, raising the dead and incomparable and exceed those of anyone else. The words of Jesus such as the Sermon on the Mount and parables and more were pure words unlike words spoken by anyone else.
