Biblical time equivalents calculated by Barry Setterfield are:-
12 Billion 5680 Creation Week (Note: not Ussher dating)
11 Billion 5680 BC (Note: Beginning of entropy)
4 Billion 4930
3 Billion 4700
2 Billion 4300
850 million 3500
630 million 3350
542 million 3300
488 million 3240
359 million 3200
200 million 3100
65 million 3000
2.6 million 2345 BC
(Some of these are rounded off : For exact figures see link below)
One billion years is equivalent to 1,000 million years. To put it in perspective, it represents a time span that far exceeds human history, encompassing significant geological and evolutionary changes on Earth. For comparison, the age of the Earth itself is estimated to be about 4.5 billion years.
yes
There are 400 million seconds in 400 million, as the question is essentially asking for a conversion of a quantity without any specific time unit. If you're referring to how many seconds are in 400 million seconds, the answer remains 400 million seconds. However, if you meant to convert 400 million seconds into years, it would be approximately 12.7 years.
0.5 of a century is equivalent to 50 years, as a century is defined as a period of 100 years. Therefore, half of that time spans five decades.
There is evidence for life on earth at least some 3,600 million years ago. So the answer is non of the above but "thousands" of millions of years.
Yes, one million years is a significant period in geologic time. It is equivalent to 1/485th of the age of the Earth (4.54 billion years). In the geologic time scale, it falls within the Quaternary period, which includes the most recent 2.6 million years of Earth's history.
a million or more years
The Devonian period lasted from 416 million years ago to 359.2 million years ago.
The Devonian period lasted for approximately 60 million years, from about 419 million years ago to 359 million years ago.
Geologic time is very long, so a million or more years is the best choice.
The Precambrian period was from 4600 million years ago to about 542 million years ago.
The answer is 63.2 million years. Since the Tertiary Period began 65 million years ago and then stoped 1.8 million years ago you have to subtract the 1.8 million from 65 million to get the actual lenght of time.
Charles Darwin estimated the age of the Earth to be several hundred million years old based on his theory of evolution. This was in contrast to the prevailing belief at the time that the Earth was only a few thousand years old according to biblical accounts.
It is highly unlikely. A million years is a short time on a geologic timescale. Earth will remain habitable for a few hundred million years into the future.
Dinosaurs first appeared about 230 millions years ago and they went extinct about 65 million years ago. Therefore the time of the dinosaurs was about 165 million years.
A million or more years best fits the concept of geologic time. Geologic time spans millions to billions of years and is used to describe the immense length of time over which Earth's processes have occurred, such as the formation of mountains, evolution of species, and movement of continents.
There was no years 85 million years ago. Man made up the idea of years, dates, or time. The dinosaur existed 65 million years ago.
