Why are scientific theories different from traditional beliefs?

Share This

Scientists work by studying the evidence collected, looking for new evidence by questioning, exiting theories, and trying to develop better ones. Traditional beliefs are a matter of faith. They are not open to question or to change, while scientific theories are. Scientific theories can be tested by using them to make predications, and then checking whether these predication come true.
Some scientific theories include the theory of evolution, the theory of relativity, the atomic theory, and the quantum theory. All of these theories are well documented, and proven beyond reasonable doubt. Yet, scientists continue to tinker with them in an attempt to make them more elegant and concise, or to make them more all-encompassing.

2) How did life originate on Earth?
Earth is estimated to be about 4.5 billion years old, and for much of that history, it has been home to life in one from or another. Today, there are several theories for how life arose on Earth. The first of these is that life was created by a supreme being or spiritual force. The second theory is that life began in another part of the universe, and arrived on Earth by accident when a comet or meteor crashed.
Scientists say that life began around 3.5 billion years ago as a result of a complex sequence of chemical reactions that took place spontaneously in the Earth’s atmosphere. Molecules were formed as a result of these reaction. The molecules then interacted with one another, and this eventually led to the earliest forms of life.
The first beings were probably bacteria which survived on naturally occurring food, and did not breath oxygen. The fossils of these oldest forms of life have been found in Australian rocks dating back 3.5 billion Yers.

3: Why have fossils given rise to many myths?
Fossils are the remains of animals or plants which once lived on the Earth millions of years ago. When fossils were first discovered, people did not really understand what they were, and so, many myths and folklore developed over time, about where fossils came from.
The coiled shells of some fossils led the Ancient Greeks to believe they were related to the ram-god Ammon. In china, these also thought to resemble horns, and were called ‘horn stones’. In England, they were believed to be coiled snacks that had somehow lost their heads, and turned to stone. Echinoids, also known as sea urchins, are amongst the most commonly found fossils. In some places, they are considered to be snakes’ eggs, which have the power to protect one from deadly poisons.
