This is part 2 of how Humans came on Earth.
Please check it in my blog. So lets start. Dinasours exist in our Earth for 14 crore years. They were in family of lizards. Then what happened how them ? Where they all got died. To know that how they died we have to go back into that time. Before 6.5 crore years ago. Earths atmosphere was normal. 4 sides trees , bright sunlight and oceans cold wind. But there was one more type of animal that was small in size and it looks like todays rats. They were our grandparents. After long period of time they were only going to be humans. They were mammals and we are also mammals. For you knowledge I am saying that dinasours give eggs. But maamals does not give eggs. That time by the fear of dinasours that mammals live inside land. When all mammals and dinasours were living a happy life. One 10km diametre's asteroid came on Earth. When it came on Earth's gravitational field its speed became more fast. As soon as the asteroid came into Earth suddenly it became a fire asteroid. Its shine was so bright that all dinasours got blind. And it smash to the ground and by the power of it the land was vibrating and ocean got on land and got tsunami. Its radiation was so powerful that all animals got fire on them and died. And then a storm came on Earth. The black clouds cover Earth from all 4 sides so sunlight couldn't reach earth. All dinasours died but what about mammals they save their life from this incident. Before some lakh years ago. Now the black cloud went down. And sun can reach Earth so plants grow up. Then the maammals were increased in their size and their look was change. This is their look. Yes, they were changed into monkey. Before 4.7 crore years ago. Now Earths 1 day was of 24 hrs. Now Earth techno plates again move and form a new land that was the same land in which we are living today when 2 land mix up 1 part of land come on second part and make a series and make himalya and by that force it make Mt. Everest. And it fall snow and by the snow melting it make rivers , oceans and seas. But something was remaining that was us humans. Before 40 lakh years ago. In africa a valley formed that was EAST AFRICAN RIFT VALLEY. And by that valley rain was not caming and in that forest our grandparents were living monkeys. They live on trees as they can break fruits and eat. But by no rain all trees dry and no fruits were their. But there were some trees left but not with fruit so they started eating leaves. They were also known as ARDIPITHECUS RAMIDUS. They were our grandparents that had taken a big decision. Their mind was as big as orange. And in height they were of 4 feet. After 1000 years they practiced to walk on 2 legs and successfull in that. Now in the time they learn how to make weapons with stone and their mind became bigger. Now they learn to make and use fire. They started making familys. They were known as HOMO ERECTUS. Now they form language and signs to supply their signals to each other. Now we know how earth form , we know that we are standing on this land how it came .
This is the part 2 ,this the last part
How humans came on Earth? Please read to know that part 1.
We humans we are so intelligent. We have science to have all answer of questions. But you know that how human these animals , dinosaurs came on Earth lets know. Earth is our home. Before 4.5 arab years ago. Pieces of one chhatan was having very much fall of asteroids and meteors. This process was going for few years and the it form a house in which we live today, Earth. And it make its own moom the Earth was made with only lava. After few years Earth temperature was cool. Before 3.9 arab years ago. Again the asteroids and meteor fall on earth that we called as THE LATE HEAVY BOMBARDMENT. This asteroids and meteor bring something that wer ice crystals that bring sea and oceans on our Earth. But life did not exist now also. Befor 3.8 arab years ago. Again asteroids and meteor fall. But they bring not only water they bring minerals also like vitamins , protein etc. Then all minerals mix themselves and make life they make bacteria. The bacterias population was increasing very fast. The sea and oceans were fully filled with bacterias. Before 3.5 arab years ago. The all bacterias mix themselves and be into a type of stone they were called as STROMOLITES. The stomolites realease something , It is the most important thing in world that was oxygen. Before 1.5 arab years ago. Now the Earth was having a Earthquick after erth quick the earths land was moving from their places and fix to each other and form a supercontinent that was called as rodinia continent. That time the one day of Earth was 18 hrs. Before 75 crore years ago. Now the Earths supercontienent was broke down. The lands downwards lava came up. By this incident the carbon dioxide increase so by the carbon dioxide the black clouds sorroumded Earth and make acid and fall acid rain. Then by clouds sorrounding of Earth it could not get sunlight the the first ice-age fall on earth. Then carbon dioxide increased and melt the ice so ice was gone from earth. But what happened to the bacteria which was in water. Before 54 crore years ago. By the oxygen of bacteria the life exist in water there were small animals in oceans the were plants also grown in sea. And there was one dangerous animal also it was ANOMALOCARIS. There were another also but they were cute and they were not dangerous there name was PIKAIA. Pikaia were 5 cm long. The Pikaia were having a life of humans they were first animal which were having bones. Before 46 crore years ago. There were no tree and plants now also because the sun was giving much sunlight. But now there will be no issue of tree and plants as by oxygen ozoen layer was creating. Now plants were growing on Earth and then one sea animal named as TIKTAALIK decided to go on land and they were successful in going to land. They practiced how to live on land and walk after few years they got legs. After getting legs they were called as TETRAPODS. Before 36 crore years ago. The tetrapods were full land animal. They were the animals which were going to be animals and dinasours and at the end humans. But now Earth's atmosphere was increased. Then again carbon dioxide increased. All plants destroyed and life on earth was 50% the some animals eat evrything that they see. And to save their life from hotness the live inside land. And after many years Earth temperature became normal. Before 20 crore years ago. Then it became a supercontinent which was name as PANGEA. Then the plant again grow and by 50% animals it grow in dinosaurs. Some were non-veg some were veg. Some were tall some were short. Some were dangerous some were not.
