First off, since God created the universe and us in his image, any other life HE may have created wouldn't be any more advanced than us...........
Even if our radio signals can be understood at the colossal distances were talking about, they havent yet gotten to a suitable candidate star.
And neither has the similar radio signals created by a race no more advanced than ours been received........
We have no real view of God’s plans, only what he chose to say to us. I don’t imagine he’d have considered any other experiments our business.
The universe is variously described as between 12-18 billion years. Our planet is considered to be about 5 billion. Now, for much of that time the heavier elements, which came from supernova explosions way after the Big Bang, were not available so, let’s say for 8 billion or so years there was no life. So, other planets could be between 4-8 billion years old. Western civilization, the one that reveres God, is only 2,000 years old. Two thousand years is an amazingly short time.
If God was diddling with other experiments and they worked a little better or faster then they could be hundreds of thousands of years old. (Remember, species on Earth only average 10,000,000 before they die.)
Potentially, there are some very old civilizations out there. But they are still subject to the same physics that make it improbable for us to ever meet.
