Let me break up some of your questions/arguments and give you some Biblical answers.
The God of the Bible claims He was there before everything. In fact already in the second verse of the Bible it is stated He was there: "Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters." (Gen 1:2) Together with John 4:24 "God is spirit, and his worshipers must worship in spirit and in truth." it shows that God was already there.
Lack of evidence? Have you ever had a look out of your window and seen how many different kind of green colours are currently on the trees? Even the Bible says that for the people who never heard of the Good News by a person who told them the Gospel could recognise that there is a God only by observing the nature. Romans 1:20: "For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse."
The Bible takes the people to a decision, that's true. Jesus says in John 14:6: "I am the way and the truth and the life. No one comes to the Father except through me." Yeah, He claims to have the absolute truth and the be only way into Paradise.
The first question I already answered above. And yes, it is a human reaction to question things, but the Bible tells humans to "trust in the LORD with all your heart and lean not on your own understanding." (Proverbs 3:5)
If that, what is told me doesn't correspond with the Bible, nothing.
Don't you think there is reasoning in the nature? If you don't then I can only tell you: "Poor you!"
And after the xxx big bangs the big bangs just stopped when the earth was EXACTLY in the correct distance to the sun that mankind can live on the planet? Sorry, but this is ridiculous. If the earth was only minimal nearer to the sun mankind would burn and it would be impossible to live here, just as if the earth was only minimal farther away. Then it would be too cold.
I also don't understand everything God/Jesus does, but I have experienced Him as a living God, who is absolutely interested in my life. And even if I don't understand everything that happens in my personal life I still know that something good will come out even of the biggest crap.
The God of the Bible clearly shows anger about the people (Ex 32:9-10) "I have seen these people," the LORD said to Moses, "and they are a stiff-necked people. 10 Now leave me alone so that my anger may burn against them and that I may destroy them. Then I will make you into a great nation.", but He also shows joy about people: "The LORD your God is with you, He is mighty to save. He will take great delight in you, He will quiet you with his love, He will rejoice over you with singing." (Zephaniah 3:17), He shows mother feelings towards His people: "Can a mother forget the baby at her breast and have no compassion on the child she has borne? Though she may forget, I will not forget you!" (Isaiah 45:15) He heals people physically and forgives sins: (Mark 2:1-12) "A few days later, when Jesus again entered Capernaum, the people heard that he had come home. 2So many gathered that there was no room left, not even outside the door, and he preached the word to them. 3Some men came, bringing to him a paralytic, carried by four of them. 4Since they could not get him to Jesus because of the crowd, they made an opening in the roof above Jesus and, after digging through it, lowered the mat the paralyzed man was lying on. 5When Jesus saw their faith, he said to the paralytic, "Son, your sins are forgiven." 6Now some teachers of the law were sitting there, thinking to themselves, 7"Why does this fellow talk like that? He's blaspheming! Who can forgive sins but God alone?" 8Immediately Jesus knew in his spirit that this was what they were thinking in their hearts, and he said to them, "Why are you thinking these things? 9Which is easier: to say to the paralytic, 'Your sins are forgiven,' or to say, 'Get up, take your mat and walk'? 10But that you may know that the Son of Man has authority on earth to forgive sins . . . ." He said to the paralytic, 11"I tell you, get up, take your mat and go home." 12He got up, took his mat and walked out in full view of them all. This amazed everyone and they praised God, saying, "We have never seen anything like this!"" These are only a few examples for the feelings the Biblical God can have.
The Bible claims clearly that there is not one good person on the earth: (Romans 3:10-12) "As it is written: "There is no one righteous, not even one; 11there is no one who understands, no one who seeks God. 12All have turned away, they have together become worthless; there is no one who does good, not even one."
HE is. But people often forget that sitting in their circumstances, which aren't always heavenly. Worship can help people to refocus on the perfect God, Who sees the circumstances, who sees the questions I have, who knows a way out of the circumstances. So worship isn't primarly FOR GOD, although He likes to listen to our worship, but more FOR US to get the focus and see again the relations... The Almighty God and my problems.
Because God doesn't want robots, but living persons to do His will volunteerly.
Every person still can decide to do NOT the will of God, which automatically ends in evil. And because even Christians, who have a relationship to Jesus, can act in the wrong way, there is so much evil in the world.
The Bible claims that man is created in three parts. There is the body, the soul and the spirit. The body will degenerate once there is no heartbeat anymore going through it. The soul is said to be the part of man that takes decisions, and the spirit is the part that is able to get the connection to God's Holy Spirit. That's the short version of it, to make it longer would extend the post even far more....
The Earth will end, but not only in million of years, but when Jesus returns to reign forever. Revelation 20:11 says: Then I saw a great white throne and him who was seated on it. Earth and sky fled from his presence, and there was no place for them." Only one chapter later it says (Rev 21:1): Then I [John] saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea."
To believe there is a better world does not take value away from this life, but gives me hope that one day I won't have pain in my knee anymore, that I won't suffer of the follow-ups of the **** I've gone through, that I will see again many dead people I enjoyed being with here on earth etc...
Quoting a book of fairytales does not constitute evidence.
