Yes, the antiproton and antineutron have both been confirmed. They were determined to exist in 1955 and 1956, respectively.
It should be noted that these particles are antimatter, and they don't just occur floating around in nature. There are nuclear reactions that occur on and around earth where the two particles are created, however. And they can be created in the physics lab with high enough energy accelerators.
Life is known for certain to exist on Earth. While there are potential signs of past life on Mars and potential for life elsewhere in the universe, Earth is the only confirmed location where life currently exists.
1.4 million plants exist on earth
The earth doesn't spin because of gravity, and gravity has not ceased to exist.
It is estimated that there are approximately 390,000 species of plants on Earth. This number includes a wide variety of plants, ranging from tiny mosses to towering trees.
Isotopes are known to exist because they are variants of a particular chemical element with the same number of protons but different numbers of neutrons, resulting in different atomic masses. These variations can be detected through techniques like mass spectrometry and nuclear magnetic resonance. The existence of isotopes has been confirmed through experimental evidence and scientific research.

Wormholes are not confirmed to exist.
Only one is confirmed as destroyed. At least 43 made it to the third decade and 23 are confirmed to exist in 2011-2012.
No, today, the astronomical community widely agrees that Planet X, as originally envisioned, does not exist.
White holes are hypothetical; it has not been confirmed that they exist, and it is doubtful they even can exist.
Vampires exist only in stories, films, and folklore.
The Pokemon regithunder is not confirmed and does not exist in the current games. You cannot get it
What caused the Earth's atmosphere to exist?
1.4 million plants exist on earth
Earth!
then we dont exist
Many scientists believe it is possible for life to exist outside of planet Earth, especially on planets with conditions similar to Earth. However, no evidence of extraterrestrial life has been confirmed. The search for life beyond Earth continues through missions to Mars and other celestial bodies.
