chemistry and philosophy "are humans a consequence ?"?

Question

Hello my major is mechanical engineering so my knowledge in chemistry is somehow limited, but i was wondering everyday people Why are we here on earth???? to what cause??. So i was thinking and i had my theorie that there is no cause for us but we are rather a consequence of the fact that atoms need to bend altogether and that is how molecules were created (because if all atoms were nobles there wouldn't be any molecules, universe...) and they in turn created acide amino than created humans blablabla. So what do you think is my theorie credible enough or should i shut up and stick to mecanichal engines...

I assume that you know what DNA is and how it allowed life forms to emerged. To answer why we are here is complicated. We are here because DNA could be formed and then life appeared. We are one species of mammals among thousands. There are no reasons to believe that we are the ultimate goal of the living process BUT WE ARE HERE! So why not doing good things? Believing or not in God is not important. Philosophers like Moses and Jesus gave us few rules for our living. They never mentioned to kill the others, steal their goods. So they are nice philosophers. The rest is not important.

Within 50 years, you will know more! Make good use of your knowledge.

Religions try to prove that life appeared 8000 years ago. The problem is that they want us to fear a god that was unable to create something simple like DNA!!! They want us to believe that not only mankind was a consequence of God's will but nothing proves it.

Life is a form of matter made of molecules and that appears in narrow conditions like those in Earth. Stars, Black Holes do not bear life. Nor molecules because their own conditions: physical phenomenons occur but not chemical reactions because of their very specific nature.

For example, bees pollinate flowers while in fact, they just want to collect pollen grains. Pollination is not the goal but it is necessary to plants.


To answer your theory All atoms are made of Electron and nucleus containing protons and neutrons. These protons and neutrons are made of quarks. Each proton is created when 3 quarks link together and energy is released.
Electrons are not formed by quarks and are different kind of particle.
Light is made of photon and waves. Photons are not really matter and are not related to quarks.
One more category of particle are bosons and one type is related to gravitation. --- Research are now oriented in the formation of quarks and boson. You should learn if there are more basic particles than quarks or not.

--- DNA created itself using gazes and from existing molecules.
So we can say that life is the latest form of matter, created via DNA (it is assumed that DNA may vary a little). DNA seems to include gaz elements. There are not real molecules in the stars, galaxies. Only gazes and dust. Life cannot appear, it requires formation of molecules in an environment similar to Earth.

The answer is that there is no evidence that life can appear without a structure similar to the DNA. Humans are only one form of livings among millions forma of creatures, plants, bacterias and others. To appear, DNA which is a polymer needed certain conditions allowed by planets like Earth and perhaps Mars. Venus is too hot and Mercury is sterile. Of course, we can't tell that Jupiter has or don't have molecular life even if there are plenty of gaz, However, temperature inside Jupiter and pressure would destroy all forms of life.

What makes humans different is self-conscience. Our brain allows us to be conscious of our environment via our 5 senses and allows us to feel emotions.
Memory is needed to learn skills. Animals are born with limited specialized skills. This is why insects and animals can perceive what we can't perceive. Plants are living as well even if we are not aware of this.

We are the consequence of the formation of DNA which allowed the formation of bacterias. Bacterias appeared as they are but we know that they merge with mitichondrias and ribosomes, two independant form of livings.
When bacterias included mitochondria and ribosome; they were able to live by their own and act on their environment.

God is not said to have created DNA, a molecule that has divine properties. And life doesn't imply the apparition of our species. In fact, our species almost disappear because of threats. In other words, God did'nt mean to create mankind itself but life emerged because four different gaz elements where found as well as Iron and Phosphor. Hydrogen and Oxygen formed water and also the Ozone layer in the upper atmosphere.
Bacterias appeared directly because DNA existed before. DNA was not protected against several threats. It is solved in water so it needed isolation and lipids was the right protection. Bacterias and all kind of cells (excluding viruses) have a lipid "skin" to avoid contact with water. As mentioned above, bacterias were living but limited. This is only when they merge with mitochondrias and ribosomes that a single cell could live, feed and reproduce itself.
Mitochondrias had their own DNA and all livings share it, including humans (There are always exceptions in order to make students mad!).
Viruses and prions are probably formed from proteinic wastes.

Because my sight is poor, I couldn't correct the text. It is redundant but complete.

Answer 2

Your theory is fine. Life exists because it can, and for no other purpose than to make more of it. But humans can choose their own purpose; Carl Sagan said: "If you want your life to have significance, do something significant." Which, in your case, probably includes being the best mechanical engineer that you can be.
