It helps exploring other options, since we are still unable to create artificial life. No one is saying to stop those experiments. But maybe they cannot succed, in the same way the alchimists could not create gold in the middle ages - because some fundamental understanding or ingredient is missing. (today we can create gold, but it is not worth it with our current technology)
"Either it was easy and formed really quickly on Earth, or space is/was so full of it that earth got contaminated almost immediately"
Or it was just random chance, that a "contaminated" comet hit earth at the right time, or an alien vessel passed by and planted life seeds. We simply don't know. So we cannot rule those options out at this moment. And "almost immediately" is still in the timespan of millions of years, so plenty of time for many asteroids to hit the earth and possibly bring life.
