Question

how did the earth come first in the universe

Answer 1

Scientists believe that our universe began with one enormous explosion of energy and light, which we now call the Big Bang. This was the singular start to everything that exists. The beginning of the universe, the start of space, and even the initial start of time itself.

Nothing we observe today existed prior to that exact moment.

Further, it was something outside of time, outside of space, and outside of matter that caused all of this to come into existence.

The realization that our universe started, and did not always exist, brings enormous challenges to nontheistic scientists.

Are scientists certain of this Big Bang Theory? Yes. In the late 1920's, astronomer Edwin Hubble saw through his telescope that galaxies (some millions of light years away) were hurtling away from each other at fantastic speeds. This was not caused by some force thrusting them away from each other. Rather, they were still moving as a result of a primeval explosion, all from one point of origin.

In
Jastrow concludes, "For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries."6

Imagine the relief of these scientists when astronomers Hermann Bondi, Thomas Gold, and Fred Hoyle advanced what became known as the "steady state" universe in 1948. Their theory was that the universe was infinite in age. Thus, no creation or no cause was needed.

Beginning of the Universe - Steady State Theory Proved False

However, in the 1960s, the steady state theory suffered a devastating blow when two radio engineers at Bell Labs (Arno Penzias and Robert Wilson) discovered mysterious radiation coming from space. It came equally from all directions. When the temperature of the radiation was measured, its source was confirmed. This radiation did not always exist, or come from one part of the universe. It came from that singular, original moment of creation.

Later, in 1996, NASA's Cosmic Background Explorer (COBE) satellite also further confirmed that the primordial background radiation pointed to an explosive start of the universe. The levels of hydrogen, lithium, deuterium, and helium that exist in our universe today confirm it as well.

Are there any scientists who still want to counter the implications of the Big Bang Theory? Yes. There are scientists who are uncomfortable living with: (1) an unknown cause or (2) the conclusion that God is the cause. So they opt for a third option.

Other Attempts to Explain the Beginning of the Universe

What explanation do these scientists give for the start to our entire universe, energy, time, and space?

They attempt to simply negate the foundational premise that science rests on: that everything that begins to exist must have a cause.
