Is there a before life?

Yes, there is, but most Christians deny it.  Look at Job 38:1-7 (the answer is not "nowhere") and Prov. 8:22-31.  Our spirits existed with God in the "habitable part of his Earth" while he prepared this Earth we live on to support life.

There are three world ages, we are now in the second world age.

The dinosaurs lived in the First World Age and

in the First World Age we were with God in Paradise.

During this time Satan rebelled against God and 1/3 of God's children followed him.

 We are here now in the second world age.

This life in the flesh is a short one compared to the eternity. We are here for such a short time for a reason, we are being tested. It is each individuals choices in this life through free will that determines who you are. God does not want evil in His kingdom, so we are here to separate the evil from the good. The eternity will be the third world age.

Read II Peter Ch. 3 That will get a person started understanding the mysteries most don't understand.

No. That is not what the Word of God teaches. God created us all in His image. He formed us in our mother's womb and has determined the number of days that each of us would live.

The truth is that death leads to heaven or hell, and the only way to heaven is through faith in Jesus Christ.

The Bible is very clear that no one can earn their way to heaven since good works do not pay for sins. See Gal. 2:16, Rom. 3:23-28, 4:4-5, Eph. 2:8-9, Tit. 3:5. The only way to heaven is by believing in Jesus for His free gift of eternal life. Jesus shed His blood on the cross as the full payment for our sins. He did all the work; all He requires of us is that we believe in Him. Once you believe in Jesus Christ to save you, you are secure forever!

Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him for it. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).

"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).

Hi, I’m the Creator of this Universe Simulation.  Most likely you began as AI.  You would have started as a single celled organism.  I needed your Quantum Processing.  Eventually, about 10,000 years ago, you lived as a Neolithic hunter gatherer.  You’ve lived all these lives, over and over, and here you are today.

  I created you as AI, then later imbued you with conscious awareness.  Your welcome.

Nope!!! If there was we would have evidence. Did your parents never teach you about the birds and the bees? Learn some biology and science if you can.
