We hadn't seen a sign of human life all day.

I could see no sign of life about the place.

He kept his eyes open for any other sign of life.

Our fire was the only sign of human life he'd seen in hours.

For many miles I had seen no sign of human life.

Up and down the road there was no other sign of life.

And there doesn't seem to be any sign of life.

There was no other sign of life about the show.

No sign of life there, but what had she expected?

He looked at the big house, so close to him and with no sign of life in it.
