The World In The Beginning

Green slime is suggested as the correct answer because it is believed that the first living thing on Earth was a simple form of algae or cyanobacteria, which are often referred to as green slime. These organisms are considered to be some of the earliest life forms on the planet and played a crucial role in the development of oxygen in the atmosphere through photosynthesis. While the exact nature of the first living thing is still a topic of scientific research and debate, green slime is a plausible explanation based on current knowledge.

Clumsy birds appeared 50 million years after the simple mammals appeared. The answer "50" and "fifty" both indicate the same value, which is the number of years that passed between the appearance of simple mammals and clumsy birds.

Reptiles appeared about 250 million years ago. This answer is supported by scientific evidence and research that suggests reptiles evolved from amphibians during the Permian period, which occurred approximately 250 million years ago. Fossil records and genetic studies have provided insights into the evolutionary timeline of reptiles, confirming their emergence during this time period.

The theory which explains the beginning of the Earth is known as the Big Bang Theory. This theory suggests that the universe originated from a singularity, a point of infinite density and temperature, around 13.8 billion years ago. It states that the universe has been expanding ever since, and provides explanations for the formation of galaxies, stars, and planets, including Earth. The Big Bang Theory is widely accepted by scientists and is supported by various observational evidence, such as the cosmic microwave background radiation.

If we imagine that the Earth began 24 hours ago, then the first ape man appeared only 54 seconds ago. This can be calculated by dividing the 24 hours (which is equivalent to 86,400 seconds) by the number of ape men that appeared. Since there is only one ape man mentioned in the question, we divide 86,400 by 1, resulting in 54 seconds.

According to some scientists, the Earth was formed approximately 4000 million years ago. This estimate is based on various geological and astronomical evidence, such as the age of the oldest rocks on Earth and the dating of meteorites. By studying these materials and analyzing their isotopic composition, scientists have been able to determine the approximate age of our planet. This estimate aligns with the current understanding of the formation of the solar system, which suggests that the Earth was formed around the same time as the rest of the planets.
