Yes.
Jupiter is the oldest planet in our solar system, forming around 4.5 billion years ago along with the rest of the planets. Its large size and location likely allowed it to form relatively quickly after the birth of the Sun.
The planets of our solar system are most definitely NOT all the same size.
NO
All of the planets are in the same atmosphere. All of the planets are unique. All of the planets are considered planets. All of the planets have moons. All of the planets are named after a mythical person or thing.
It depends on your religious belief. But scientifically, a long time ago, gravity pulled matter in all directions, and over time, became planets. YES. The first answer is not scientific. There is more evidence for creation than "gravity pulling the planets together" such as the laws of Thermodynamics, which state that order (planets) cannot come out of disorder (random gravity and matter). Also, since matter bends space and time (Relativity), matter could not be pulled into planetary forms unless someone (God) created matter, time, and space at the same time.
Planets are not alive. Theory suggests that all the planets were created at the same time.
In all probability, all the planets are about the same age. They formed around the same time as all of the other planets give or take a few million years.
"No"

Star of All Planets was created in 2003.
All the planets of our solar system are believed to have formed at about the same period in time.
The planets formed out of the solar nebular there is no concept of the "first" they all formed slowly at the same time.
The planets of our solar system are most definitely NOT all the same size.
there are no inner gas planets only outer gas planets but they are the same because they all have rings, they are all made of gas.
The planets must all have formed at approximately the same time.
all planets.
Do all planets and satellites lie on the same gravitational layer?
