Explanation:
Life-form might have come before oxygen appeared 2.5 BY ago.
It came as single-cell bacteria that need no oxygen or water., to live
as such, for thousands of years.
This unicellular life-form could have been transported to the Earth
from some other space bodies, when they braced, brushed or
impinged on the Earth.
If so, the region from where life started on the Earth might be a local
region or a spherical narrow band upon the Earth.
