It’s amazing the lengths NASA et al goes to in order to convince the general public that the Earth is round.

Detecting ANY form of life would already be a breakthrough. It doesn’t have to be an exhaustive survey of everything in the galaxy and beyond.

It’s not round it’s an ellipsoid. 
True. If we can kidnap one form of life, we can make it tell us what else is there. 
although earth is indeed an oblate spheroid , the difference is only .3 % , soo calling it a sphere is really close enough for most purposes ;
3 parts out of a thousand is difficult to measure , a golf ball sized sphere with such an aberration would be outside of the skill of most people with most micrometers to measure < or so it is alleged !! )
