The earth is roughly 4.5 billion years old, give or take a few 'earthdays'.
6.5 Billion years ago.
The way the universe works now is the same as how it did in the past, as well as how it will work in the future, which is unverifiable and therefore must be assumed. Some examples: - Scientists assume that there is no way to secure complete and absolute truth - Secular scientists assume that the earth and universe were not created supernaturally. - Scientists assume that natural laws we identify will apply to all of the universe - Scientists assume that they all work towards the common good - Scientists assume life can evolve on earth in the presence of water - Most scientists assume near-death experiences and out-of- body experiences are a result of a lack of oxygen in the brain
Scientists hypothesize that chemical events preceded the origin of life on Earth because these events could have provided the necessary building blocks for life to form, such as organic molecules and simple compounds. By understanding how these chemicals interacted and evolved over time, scientists can gain insights into the origins of life on our planet.
Scientist theorize that a planet-sized object collided with earth and the moon formed
Earth scientists assume that the causes of natural events or phenomena can be determined by observing patterns, collecting data, and analyzing evidence. They use methods such as experimentation, modeling, and field studies to understand the underlying processes driving these events. By studying these factors, scientists aim to develop theories and explanations that can help predict and mitigate future events.
Scientists study deuterium in water because it can provide clues about the origin of water on Earth. Deuterium is an isotope of hydrogen that can help differentiate between water from sources like comets, asteroids, or Earth's mantle. By analyzing the deuterium content in water, scientists can determine where that water may have come from in the early stages of Earth's formation.
Scientists have fossil evidence supporting the idea that life originated from simple, single-celled organisms that emerged over 3.5 billion years ago. Fossils of these early microorganisms, such as cyanobacteria, provide insights into the evolution of life on Earth.
Titan, one of Saturn's moons, has a thick atmosphere and surface conditions that resemble early Earth. Scientists believe studying Titan may provide insights into how the building blocks of life formed and evolved under different conditions, potentially shedding light on the origin of life on Earth and elsewhere in the universe.

the god! SCIENTISTS GOD dont exsists you stupid div
Cosmology
Scientists who study earth's oceans are called oceanographers.
