To say that the Big Bang occurred in a particular shape is probably not an accurate description, because the expansion of the Universe is an expansion of space itself, not the stuff inside it, like the Earth or the Sun, or the Milky Way Galaxy, or anything else.
If you imagine that the Universe is the surface of a balloon, then when the Big Bang happened, it is like the ballon being blown up. Every point on the ballon is expanding way from every other point. And if you were living inside this 2-D universe, you wouldn't be able to say what "shape" the Big Bang explosion was, because you will see everything moving away from you, as if you were at the center, But you know that there is no center on the surface of a ballon. This is exactly what it is like for us, even though we are living on the 3-dimensional surface of a 4-dimensional sphere (actually, there maybe more spatial dimensions, but that's another story related to String Theory).

"In physical cosmology, the Big Bang is the scientific theory of how the universe emerged from a tremendously dense and hot state about 13.7 billion years ago.
Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density.
Since the discovery of the cosmic microwave background radiation in 1965 it has been regarded as the best theory of the origin and evolution of the cosmos.
Approximately 10â35 seconds after the Planck epoch a phase transition caused the universe to experience exponential growth during a period called cosmic inflation.
As the universe continued growing in size, the temperature dropped.
Still lower temperatures led to further symmetry breaking phase transitions that put the forces of physics and elementary particles into their present form.
After about 300,000 years the electrons and nuclei combined into atoms (mostly hydrogen); hence the radiation decoupled from matter and continued through space largely unimpeded. This relic radiation is the cosmic microwave background.
Over time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and thus grew even denser, forming gas clouds, stars, galaxies, and the other astronomical structures observable today.
A possible resolution to this problem is again offered by inflationary theory. During the inflationary period, spacetime expanded to such an extent that any residual curvature associated with it would have been smoothed out to a high degree of precision. Thus, it is believed that inflation drove the universe to be very nearly spatially flat."
Wow. Tough problem. But it seems that current research says the answer to your question is "No, it was not a globular shape."

There was no big bang so it didn't have a shape, see link below.
Generally it is agreed, even by those that believe in a big bang, that the size of the universe is unknown and may be many times the distance to the event horizon at 14 billion light years. The earth is a very small segment of the universe, representing only 0.000000 000000 000000 000000 000000 000000 000000 000000 000000 000000 0000001 of the volume of the observable universe. Kind of makes you feel small doesn't it?

The "Big Bang" is not an explosion as we think of things that go boom. It was an expansion of dimensional energies without boundaries. The Universe does not have a shape in the usual sense. It is a tourus of multiple dimensions floating on a super multiple dimensional membrane interacting with other super multiple dimensional membranes.
The Earth is a custom made planet created for pan dimensional beings by the planetary engineers on Magatharea to solve the question of Life the Universe and everything to make sense of the answer 42.

The earth formed from cosmic dust many years after the big bang. And yes, to the universe, the earth is nothing more than a grain of sand.

yeah, if you think about it, Earth is just a tiny bit of metior or space rock thing in Earth, but then confusion.... God made it too
