No, not "like everything else". The "lifespan" of a human is not really defined in the same ways as the "lifespan" of a virus, or a planet, or a decomposing chemical. So it depends how you define the "death" of the earth.
Regardless of what the ecosystem is like on the surface, the planet will eventually be consumed by the sun as it expands (which all stars eventually do). So yes, there will be some point in time that the earth will cease to exist as a planet. That sure isn't going to happen for a while though.

That is a mighty fine question you ask there. Nothing lasts forever right? All good things come to an end. Never say never. No means yes. In all seriousness to answer your question, in a few trillion years, the sun in its final days will expand and then collapse on itself. Those will also be the final days of the earth. So yes, the Earth does have a lifespan.

Like everything in time, all things will end. Stars go nova all the time in the universe, others are born every day, and we have only seen a small few, and it is not any different for the Earth.
With our Sun, it has an average life of about 11 billion years, and was formed around 6 billion years ago, so when the Sun goes nova in 4.5 billion years, you can pretty much say good-bye to everything in Solar (Sol).

Yes, Earth is an average non stellar body. Geologists have calculated in 5 billion years the age of our planet, in 9 billion yers the age of the solar system, and 20 billion years the total lifespan of the whole thing.

The Earth isn't really alive in any way we understand. But if you want to push the analogy, the Earth doesn't really need us to endure. In the early days, its atmosphere was larely carbon dioxide and wouldn't support human life. It has "seen" whole phylums of animals come and go. As far as it is concerned, we are just one more species. We could all die out from pollution or climate change and the Earth would cope just fine.

Like everything else in the universe the earth will run it's course and die.
The universe that contains everything that we see and experience will one day go out of existence and everything else with it.

Of course. It's scheduled to be swallowed up by the sun in like a billion years from now.

I seriously do. I am not a scientist, but a regular human type. The earth's core is constantly changing. How long can it stay liquid? I wonder myself.

Of course. Our planet can't be around until the end of time. Eventually it will be destroyed in one way or another, more than likely sometime after our Sun dies.
