Without the Big Bang there would be NOTHING. The entire Universe - including space, and apparently even time! - is the result of the Big Bang.
The big bang theory has nothing to do with the formation of planets.
Everything happened after the big bang.
Neptune came from the big bang like the rest of the planets it was formed by all of the gasses that were let off when the big bang happened.
It all started with the Big Bang. All the matter created from the Big Bang eventually formed planets and every thing else. From the moment matter was created during the Big Bang the matter was expanding and moving really fast. So eventually all the planets and stars and galaxies that were formed started to spin around each other from the velocity that was created.
Nobody created the planet. It formed by the gravitational accretion of smaller objects.
If the Big Bang never took place, the universe as we know it would not exist. The universe began as a singularity and expanded rapidly from that point. Without this event, there would be no galaxies, stars, planets, or life as we know it.
All the planets in our solar system formed at about the same time, 4.5 billion years ago. That was about 10 billion years AFTER the Big Bang.
The Big Bang did not directly create Earth or any other planets. The Big Bang theory describes the initial expansion of the universe and the formation of fundamental elements. Planets formed later through processes like gravitational attraction and accretion of matter in solar systems. Each planet's formation is a result of its unique conditions and history.
It was formed by the big bang but nobody knows how it was formed or what there was before the big bang
The Big Bang Theory represents the creation event for our existence in a traditional fourth dimensional SpaceTime continuum. Without this environment, there would be no galaxies, solar systems, or planets. So while the Big Bang Theory provided for (or made) existence within the universe, the actual formation of solar systems and resulting planets would be more accurately present in the Nebular Hypothesis (sometimes referred to as the Nebular Theory).
Probably several tens to hundreds of millions of years following the Big bang. Afterwards, planets formed around stars and became a permanent feature of the Universe.
