If there really was a Big Bang, then we would also expect all of the planets and moons to rotate in the same direction on their axes. However, Uranus and Venus both rotate backwards. Also, eleven out of the fifty moons in our solar system orbit in the opposite direction. We would also expect to see the orbits of the moons to lie flat over the equatorial planes. We would also expect to see the sun's inner planets made up mostly of hydrogen and helium, just like the sun.
Many evolutionary astronomers teach that somehow atoms created themselves.
From this gas, all life originated from a super explosion that happened some 12 to 15 billion years ago. After that explosion, the universe became increasingly more and more complex. The sun and all the other stars eventually condensed out of gas. Then these gases condensed into dust particles, which somehow got together and formed all the planets. Eventually, this matter turned into water, and then dead matter actually became a living creature.
