If a fetus is a human being, how come people say ' we have two children and one on the way ' instead of saying ' we have three children? ' People say life begins at conception, I say life began about a billion years ago and it ' s a continuous process.

It ' s not unlike the way life started in the oceans four billion years ago

These are distant luminous infrared galaxies, and appear as they did 10 12 billion years ago, packed together like grains of sand on a beach, forming large clusters of galaxies by the force of their mutual gravity

This pyrophyllite (Al2Si4O10 (OH) 2) is a quite soft secondary mineral with a count of only 3 on the Mohs ' scale and was formed by sedimentation about 2.8 billion years ago.

- Universe is 13.7 billion years old, with a margin of error of close to 1 %

The supercontinent before this was Columbia: 1.8 to 1.5 billion years ago.

And before this was Kenorland: 2.7 to 2.1 billion years ago.

Ur existed 3 billion years ago and Vaalbara 3.6 to 2.8 billion years ago.

It is also a cosmological model in which the universe has been expanding for around 13.7 billion years (13.7 Ga), starting from a tremendously dense and hot state.

This account of the history of the universe is simplified, because it ignores quantum mechanics: at a point in time called the Planck time (now thought to have been 13.7 billion years ago), the universe was small enough to be subject to quantum mechanical effects.

We are the product of 4.5 billion years of fortuitous, slow biological evolution.

But how could the Earth continue to move at the same speed for as long a time as the " round Earthers " say that it has existed for; namely, several billion years.

15) Traces of hydrocarbon gases at mid ocean ridges (such traces are not surprising given that the upper mantle has been contaminated with biogenic organic matter through several billion years of subduction, the answer to 14 may be applicable also)

Even if a supernova a billion years ago did create some quantity of an element such as Berkelium, number 97, there would be none left in the Earth ' s crust today.

" Their computer models predict planetary motions into the distant future and they find a small probability for collisions of Mercury with Earth or Venus sometime in the next billion years or more.

Prof. Bignumska calmly replied, " About a billion years.

At that speed, the gigantic void-and-shell pattern appears to have taken at least 150 billion years to form, which is seven to ten times the number of years since the Big Bang allegedly took place.

Of those, six are about a billion years or more old.

We have known for twenty-five years that Einstein ' s general theory of relativity predicts that time must have had a beginning in a singularity fifteen billion years ago.

Prema tvrdnji NASA-e, smatra se da je prvih 500 milijuna godina Mjesec normalno evoluirao, a potom su rekli (New York Times): " The most cataclysmic period came 4 billion years ago, when celestial bodies sthe size of large cities and small countries came crashing into the Moon and formed its huge basins and towering mountains.

The dolerite is believed to have existed as much as 1/2 billion years before the meteorite impact.

From an evolutionary perspective, each of us is the result of a series of continuous living identities stretching back for at least three billion years.

We are also life and matter in continuity for 13.7 billion years.

Peter Moon goes on to say, " A half billion years ago, the Aryans (known as the Elohim or Elder Race) began to colonize our solar system as Aldebaran became uninhabitable.
