    Default Based upon your knowledge of the Earth system, the planets in our solar system?



    and the cosmos in general, speculate about the likelihood that extra-solar planets exist with atmospheres, hydrospheres, lithospheres, and biospheres, similar to Earth’s (including the possibility of other life forms) Explain your speculation.

    There is nothing identical to life on Earth, so I would suggest looking after this Earth.

    There are many other solar systems, planets, atmospheres etc with and without life, but none of these are to be compared to planet Earth.
