Scientists can create life in laboratories.
Not things like that because there's too many cells in them. But very simple life.
A simple cell would be like a bacteria - bacterial cells (prokaryotes) are more simple than other types of cells (eukaryotes). For example, in bacteria the DNA just floats around in the cytoplasm, but in eukaryotes the DNA is encased in a membrane, the nucleus. So scientists who are trying to make life are going to start with the simplest kinds of known life - the bacteria. Basically they can try and make a bacteria from scratch or they can take existing bacteria and work backwards...removing non-essential parts until they are left with the most simplest cells. At this point they can try to build those simple cells from scratch, working their way up to a more "complex" bacterial form. The idea is there, the execution isn't quite there yet.
My understanding is that they can basically make pretty much all the simplest components of a cell (e.g. DNA, lipid bilayer, proteins...) but they can't get it to become alive. We understand most of the underlying mechanisms and requirements to make a simple cell go, but we can't seem to build one from scratch. We can for example, take the DNA out of an existing cell and place our own machine-made DNA into the cell and it lives. But we can't seem to start with nothing.
In other words its like we are able to make all the components for a watch (e.g. gears, screws) but we can't seem to put it altogether in such a way that makes the clock tick. However, can take out a couple of gears and screws from a existing watch, put in our own fabricated gears and screws and get the watch to tick again.
Scientists who study this are trying to understand abiogensis. There are many different approaches. I wouldn't be surprised if in a few years or decades we have managed to create the first simple living cell.
