Is there life on Mars?

According to the current technology, life has not been detected on Mars, but it is still possible to have life on Mars.

For hundreds of millions of years, Mars is not an unpleasant place. It has liquid water. But if life evolves on Mars, rocks will be hit by asteroids from time to time. At some point, rocks from Mars may hit the earth.

If the earth's environment at that time happened to be very suitable for the development of life, then Martian rocks might be the initial beginning of life on earth. But this is just a theory and can be tested. However, unlike the earth, Mars has an ancient geological record, but it is very difficult to detect.
