Countries that seek to leave an imprint in the human scientific history take care of their languages by making them the official languages of educational channels and scientific publications while promoting them at international forums. Semantically and scientifically speaking, there is no language more scientific than another, but it is the interest, economic and scientific advancement and achievements, investment and innovations that make a language more scientific than another. All languages can ultimately be scientific and suitable for the dissemination of scientific findings and thoughts, including the least spoken language when native speakers get involved in. Nobody can deny the importance of English as a lingua franca for business, communication and science, and the need to learn it is paramount. Nonetheless, there is a difference between learning and mastering a language and replacing it completely with another language. It is good to learn as many languages as possible but this should not be done to the expense of local languages. There are more than ~ 7000 languages in the world, and English cannot- shouldn't- replace all of them, as language diversity is as important as biodiversity, if not more. With a few exceptions only, most countries in the world teach and publish science in their own languages along with teaching and learning English but in the Arab world scientific institutions and universities did not succeed, neither in adopting English nor in preserving their own language. Instead, indigestible and incomprehensible dialectal mixtures have been born, and many call to replace Arabic with other languages at academic and educational levels. Publishing science in Arabic is also very scarce compared with other languages that are less spoken than Arabic.
