Get a handle on your orders of magnitude. We have not sent any probes a billion miles looking for life. (a billion miles from the sun would be someplace between Jupiter and Saturn).
Try hundreds of millions of miles. (Earth to mars 35 million miles to 250 million miles).
We have sent probes billions of miles, but not specifically looking for life.
