Life Beyond Earth
The two gases — dimethyl sulfide, or DMS, and dimethyl disulfide, or DMDS — involved in Webb’s observations of the planet named K2-18 b are generated on Earth by living organisms, primarily microbial life such as marine phytoplankton — algae. These albeit living entity, are not in any way intelligent lifeforms like humans/angels/jinns. What Quran means by saying seven heaven and seven earth is that, each heaven contains an earth like planet (as in having intelligent lifeform, blessed with reasoning and free will). Also, this nuanced interpretation of the verse differs greatly amongst scholars, some say the number seven, signifies largeness/infinitude instead of a fixed quantity. Maududi (RA) also thinks that this could be seven different heaven and earth or seven imaginary bifurcations of our one universe.
