Abou the Earth.

Some people, when discussing and discussing a topic, clearly confuse opinion based on theories that have not been proven true, and the parameters that are fully scientifically agreed upon;  The first holds opinions and increases and decreases objectively, while the other does not bear opinions, because they are fixed and well known.  For example, when there is a debate about the existence of another life on other planets in space, some completely deny the possibility of a life other than the Earth, and mobilizes to reinforce its opinion every possible argument from the sayings and theories of scientists, and there is a team that finds it self-evident that there are aliens and other life,  And that the expansion of the universe and the ignorance of man does not mean denying or rejecting the existence of another life.  Between the two teams, others struggle over aspects like having an intelligent or backward life.  In such a case you cannot claim the ultimate truth no matter how excited you are your point of view;  There are issues that are admissible and intolerable for different opinions such as one of them coming and saying that the Earth is flat and not spherical, because the Earth's spheres were proven before a person ascended to space, then these scientific proofs were reinforced through the many and many images, and through hundreds of astronauts who head  To space on frequent and consecutive trips, and today we have a live broadcast from the space station in our hands to pictures of the Earth, then you hear those who question and say that his view is that the Earth is flat! .. Usually the opinions tolerate right and wrong, and can adopt an opinion and then after a period of change, especially after study  And research, and this is normal in the scientific corridors, and, as the Spanish proverb says: "The world changes its mind, but the stupid is stubborn."  What I mean is that it is not a shame to retract from what you see, especially it is not a proven fact, but the defect is really, and it is a sign of ignorance that conflicts in the proven facts that the world has overlooked.
