While delivering a lecture at the University of Life Sciences, Lublin, Poland, I stated that “we eat DNA every day”, now the question arises who makes tons of DNA for all of us, obviously, Mother Earth. As human mothers before conceiving a child prepare her body to nourish the offspring, Mother Earth also did the same thing.
The Sun who is about 7 billion to 8 billion years old gave birth to the Earth. The Mother Earth’s birth was a big event. Earth was formed when gravity pulled swirling gas and dust in to become the third planet from the Sun about 4.54 billion years before plus or minus about 50 million years. These estimations have come from the affords made by Scientists who have scoured the Earth searching for the oldest rocks to radiometrically date. As it is said those who have taken birth have to die and therefore Mother Earth has also to die Earth has at least 1.5 billion years left to support life If humans last that long, Earth would be generally uncomfortable for them, but liveable in some areas just below the polar regions.
What makes the Earth habitable?
It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Microbes to Dinosaurs to Humans
Earth's amazing gaseous atmosphere is responsible for making life possible on this Earth, the third planet from the Sun. Our atmosphere contains water vapour which helps to moderate our daily temperatures. Our atmosphere contains 21% oxygen necessary for us to breathe, 78% nitrogen, and 9% argon. All living things need some sort of food, water, the right atmosphere and temperature. Humans, for example, need to breathe in oxygen and can survive in temperatures that aren't extremely hot or cold. Even the strength of gravity determines the form of our bodies such as our bones and muscle strength. Our planet became habitable and life emerged during its first 500 million years ago. There is no question that Earth has been a giving planet. Everything humans have needed to survive and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things. The Permian is a geological record that began nearly 300 million years ago, almost 50 million years before the Age of the Dinosaurs. During the Permian, the first large herbivores and carnivores became widespread on land. The Permian ended with the largest mass extinction in the history of the Earth.
Plants lined the way for the evolution of land animals by simultaneously increasing the percentage of oxygen in the Earth's atmosphere and decreasing the percentage of carbon dioxide, a powerful greenhouse gas. The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe two million years ago Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They're followed by anatomically modern Homo sapiens at least 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago.
These early humans probably had pale skin, much like humans' closest living relative, the chimpanzee, which is white under its fur. Around 1.2 million to 1.8 million years ago, early Homo sapiens evolved dark skin.
Do humans come from monkeys?
Humans and monkeys are both primates. But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago.
Sanātana Dharma has been called the oldest religion in the world. Sanātana Dharma has no single, known founder, unlike other religions. Nor is there a particular date for its “founding.” It seems to have emerged gradually, out of elements already discernible roughly 3,500 years ago.
The first and foremost of these is a belief in the Vedas – four texts compiled between the 15th and 5th centuries BCE on the Indian subcontinent, and the faith's oldest scriptures – which make Hinduism without doubt the oldest religion in existence. (The author has his own study and views)
