When was the earth born?

Question

what was the exact date and time the earth was born

Answer 1

Impossible to say. Ignoring that fact that the date and time systems we are familiar with are entirely human constructs, we simply can't measure it with that degree of precision, and besides, what point do you choose as the "birth" of the Earth? When the nebular cloud of our solar system began to collapse? When the first planetesimals on our orbit began to accrue? When it became large enough to become spherical under its own gravitation? When it reached a similar size or mass to what it has today? When the smaller planet that collided with us and threw out the material that went on to form the moon hit? When the crust solidified (bearing in mind parts of the crust aren't solid even today)? When the atmosphere was formed? These all took place at different stages in the Earth's formation, a process that was continuous and took a long time. The closest we can get to an answer is 4.55 billion years, give or take 1%, which is the age of the solar system based on radiometric dating of meteorite material that also formed during the accretion phase of the planets.

Answer 2

With current levels of technology and scientific understanding, there is no possible way to even come close to answering that question.  The best anyone on this planet can do is guess and, even then, the basis of their hypothesis is hinged on human theories that are based on other theories balanced upon other theories.  If any one point along the line fails, the entire timeline guess would collapse.

So, let's just say that it is somewhere between 6,000 years and 6 quadrillion years old (give or take some).  Of course, even that requires us to assume that the term "year" is constant and definable, which is a fact that science has already proven to be false.

Only God knows for sure.  He was there when it happened.
