I don't have to prove anything is where you're not understanding. The millions of believers have faith, and that's all we need. Science has proven nothing of if a God exists or not, and the universe has a creator, unlike what some of them think. I was never taught God was in the sky but everywhere. That he's in another dimension is obvious to me and others. As always, different people think of different things. God obviously made more people after Adam and Eve but they were the first modern humans.There is also this.........Sibling or Close Relative (Literalist View): The most straightforward explanation is that Cain married one of his sisters or nieces. Because the world's first family had no other people to intermarry with, these unions were necessary for humanity to grow. Biologically, incest at this time would not have carried the genetic risks seen today because Adam and Eve were created with perfect DNA, making mutations non-existent in the initial generations. Pre-Adamic or Separate Populations (Alternative View): Some interpretations suggest that other distinct populations of humans (sometimes referred to as pre-Adamic humans) lived outside the Garden of Eden. In this view, when Cain was exiled to the land of Nod, he encountered and married a woman from one of these other groups. I always believed it was behind door number 2. No, the Bible does not explicitly state the age of the Earth. The widely cited estimate of roughly 6,000 to 10,000 years comes from calculating and adding up the generational lineages, ages, and timelines recorded in biblical texts, most famously calculated by Archbishop James Ussher in the 17th century. Because this number is the result of external human calculation rather than a direct statement, there are varying interpretations among Christians regarding the age of the Earth: Young Earth Interpretation: By calculating genealogies (like those in Genesis 5 and 11) and interpreting the "days" of creation literally, many scholars estimate the Earth to be approximately 6,000 years old. Proponents of this view believe God created dinosaurs alongside humans on Day Six, meaning they did not live millions of years ago Old Earth Interpretation: Many Christians and theologians accept the scientific consensus that the Earth is 4.5 billion years old. In this view, dinosaurs roamed the Earth millions of years before humans existed, and the creation days in Genesis are interpreted as representing long, figurative periods of time rather than 24-hour days. I see that it's actually you that has a closed mind, as mine isn't that way and never has been. That I choose common sense and faith and you go by a few other's opinions shows it well, so again, stick to the topic, seeing you aren't reading but skimming.
