I’m a believer in the idea that the earth formed from bits and pieces of debris in the solar system about 5 billion years ago, with life starting on earth about about half a billion years later, which has been evolving since then. Regarding the evolution of species, I think that Darwin got it mostly right.
according to astrophysicists the earth was made about 4.6 billion years ago, and is a lot younger than the universe (about 14 billion years old).
It is possible that a nearby supernova caused a shock wave which caused interstellar dust and gas to rotate and develop gravity. Most of the mass concentrated in the middle began to heat up (becoming the sun), dust particles formed rings around the sun – larger pieces began to collide and form together into planets including the earth. It took about 15 million years for the earth to form.
At some point simple cells started floating around in the sea, then these developed into more complex cell based life, which gradually developed into the first animals – sponges seem to be the first animals and they seem to be able to propagate by fragments of them falling off and developing into new sponges. Things gradually got more complex from there until we reached animals that actually give birth.
